What is Solar?

Any form of energy radiated by the sun, including light, radio waves, and X rays, although the term usually refers to the visible light of the sun. Solar energy is needed by green plants for the process of photosynthesis, which is the ultimate source of all food. The energy in fossil fuels (e.g., coal and oil) and other organic fuels (e.g., wood) is derived from solar energy. Difficulties with these fuels have led to the invention of devices that directly convert solar energy into usable forms of energy,such as electricity. Solar batteries, which operate on the principle that light falling on photosensitive substances causes a flow of electricity,

play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth.

Thermoelectric generators convert the heat generated by solar energy directly into electricity (see thermoelectricity). Several projects have produced electricity on a large scale by using the solar energy available in desert areas. In one system, large numbers of solar batteries generate electricity for Coconut Island, off the coast of Australia. In another, oil flows through pipes that are set in reflecting parabolic troughs that can trap the heat from sunlight falling on them. The heat from the oil is then converted into electricity.

Heat from the sun is used in air-drying a variety of materials and in producing salt by the evaporation of seawater. Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container. Such systems, however, usually require a conventional heater to supplement them. Solar stoves, which focus the sun's heat directly, are employed in regions where there is much perennial sunlight. See also energy, sources of.

Solar cells, also referred to as photovoltaic cells, are devices or banks of devices that use the photovoltaic effect of semiconductors to generate electricity directly from sunlight.

Until recently, their use has been limited because of high manufacturing costs. One cost effective use has been in very low-power devices such as calculators with LCDs. Another use has been in remote applications such as roadside emergency telephones, remote sensing, cathodic protection of pipe lines, and limited "off grid" home power applications.

A third use has been in powering orbiting satellites and spacecraft.energy.

Solar panels work by converting light directly into an electric current. PV solar panels only require day light not direct sunlight but may only produce 20% of peak power rating.

A solar panel is made up of several photovoltaic cells, these cell are connected together in series, to boost the current. A photovoltaic cell consists of two types of silicon P-Type and N-Type. The surface of the cell is transparent so the light can pass though and fall onto the first layer of silicon.

This layer of silicon has been manufactured to be positively charged. Likewise the other layer of silicon is made to be negatively charged. When sunlight falls onto the cell a flow of electrons is created though the cell causing an electric current.





PV System sales & Installation sequence of events.

A) Home or business-owner have a good site, financing viable. Evaluate utility bills.
B) Site visit- Evaluate of site, sizing of system space available, system cost, layout and lengths of runs, verification of service voltage and bus rating in Amps.
C) Sign contract/deposit – Commitment to project, scheduling and billing expectations. Permitting and engineering fees (if required) additional to installtion cost.
D)
  Contact the Utility – Initiate the utility company paperwork. Either the costumer needs to fill this out, or with their authorization, we can do this on their behalf.E) Apply for permit with AHJ – Submit system diagram and cut sheets for all major components (sometimes several copies are required).Occasionally the building department may request the planning department to approve prior to the building department permit being issued.Some cities and counties have simplified procedures and reduced fees.
F) Delivery of Components – Coordinate with Customer for delivery of the components to the jobsite. Arrange for payment at time of delivery.
G) Installation – We will stall the system as required by NEC and local codes. Pay special attention to labeling requirements in NEC 690.17 and 690.53
H) Inspection and Permit Completion – Once the installation is completed and permit is approved, notify the utility that the system is ready for their inspection. (in some cases the building dept will notify the utility) After they do inspection, written notice will be sent to the customer and the system may be turned on.
I) Submission of Paperwork for Final Rebate check – Allow approximately 4-6 weeks for processing of claim form First we need to make an appointment To discuss your needs for having Solar Power Energy and choose a best possible site for installation of Solar Panels.
Our systems consist of an array of solar panels, an inverter and a computerized solid-state controller. The solar electric panels convert sun light in to electricity that you could in your home. The Inverter converts the DC electricity produced by the panels to AC electricity. The computerized controller regulates the system and directs your extra power back to the utility grid.
In applications where you are not connected to the grid or you want back up power, batteries are required.

STAGE1 Calculations
What Size Solar System Do I Need?
Our system require approximately 100sq. ft. of panel area to generate 1000 watt of electricity. An average 2,500sq ft single-family home uses about 5,000 kilowatt-hours of electricity per year A 3,000 watt (AC) system, using 300 sq. ft. of roof space, will generate nearly all of the electricity required for such a home on an annual basis.
Our poser systems are clean silent, and have no moving parts. In utility interconnected applications, the reduce the need to move power over aging transmission lines producing solar electric power where it is used and sending the excess power into the grid from thousands of decentralized points is helping us change the way power in produced and distributed.

SATAGE2 Upon Agreement
After reviewing the information presented in the package and Once we are agreed on the sale price and contract signed we will help you to fill out necessary forms for permits, rebates, tax credit and so forth,,,,

STAGE3 Installation
The systems include all of the major components required for standard installations.
Site-specific variations dictate that some standard electrical items and options cannot be determined until the lengths of the wire runs and equipment location are determined. Some additional options available from Smarthome Ideas.
All our systems include the following: solar panels, flush mounting hardware, ground lugs for the rails of the mounting system, module interconnects, output cables to the combiner or rooftop junction box, the combiner box or junction box, series fusing for each parallel string ( when required), ground fault protection for array, the inverter, AC disconnect accepted by utility companies.
Additional items you will need to determine and buy are:
The AC breaker, wires and conduit for the main panel for your grid connection at main panel, the conduit and wire for the connection of the combiner or junction box at the array to the power center (UB systems) and the grounding wire.
Smarthome Ideas only uses highest quality fasteners, conduit and components since the modules do have a 25 year warranty. We do not use zinc plated or galvanized hardware. Stainless is preferable.AC wire runs should be sized for 1% voltage drop maximum.
AC wire and breakers should be sized for maximum AC amperage  X 1.25 (for continues circuit correction)
The AC bus of the customer’s Service Panel must be adequately sized to accept the solar breaker.
Combined AC Sources (main utility breaker $ solar breaker) should be less than 120% of the buss rating. We Locate AC disconnect Switch within 10 feet of main service/meter location.

STAGE4 Final Completion
At this point we will call utility company to inspect and turn-on the system




Do I Really Need One?

Do I need it? This question really comes down to:
A: Do you want to save money on utility bills?
B: Do you want to have a Energy Independency?
C: Environmental Friendly
D: Depending on foreign oil

We have created many problem to this planet of ours,,, We all have responsibility try to make it a better place to live on without any consequences, but as humanity grows and evolves the problems with environment grows as well, if we are aware of our action and don’t let greed get in the way,,, we will do just fine not just to our selves but to the environment that sustain us. If its not NOW or Never.



California Solar Incentive Program

California Solar Incentive Program

What are Incentives?

Solar energy is one of our state's most abundant - and least utilized - renewable resources. As part of Governor Arnold Schwarzenegger's Million Solar Roofs Program, California has set a goal to create 3,000 megawatts of new, solar-produced electricity by 2017 - moving the state toward a cleaner energy future and helping lower the cost of solar systems for consumers.


CaliforniaSolar Initiative (CSI) Rebate
The State of California is presently offering a $2,500 cash rebate for per 1,000 watt cash rebate for solar electric systems that are connected to the utility grid. Upon signing a sales contract, Smarthome Ideas will submit a reservation for you after receiving a deposit on your solar system.
Once the utility company receives the application for an eligible system, they will send you a claim form showing the rebate dollar amount reserved in your name.
Once your system has been permitted, installed, and is operational, the claim form and your final inspection approval will be submitted to the utility for payment.
Within 30 to 60 days, the utility will mail your rebate check.
The incentive level does drop over time as more customers take advantage of it, so if you are considering solar, the best time to do it is NOW.

New Federal 30% Solar Tax credit
Additionally, a 30% tax credit is being offered on all solar systems installed before December 31, 2008 for residential applications, there $2000 cap; no cap for commercial applications.

California Property Tax Exemption

Credit includes equipment, installation and labor cost
Expenditure eligible for credit upon completion of installation (“placed in service”)
Credit given on the cost of system after any state or local rebates are deducted
If the taxpayer does not have enough tax liability in the first taxable year to take full advantage of their credit, they may carry forward the credit to the following tax year





Facts on Solar

Solar electric power is a renewable source of electricity that is available in any part of the world. Understanding the advantages and disadvantages of solar power will help you determine whether to switch to solar or continue purchasing electricity from the local electric company.
Understanding the advantages and disadvantages of solar power does not require you to have complete understanding of
the entire solar electric system.
You do not need to be able to calculate the voltage loss for a 24 volt system or calculating the correct size of an inverter. Understanding the advantages and disadvantages of solar power can provide you with a clearer perception on how a system works to keep utility bills low, preserve fossil fuels and reduce pollution.
What are the financial considerations for a solar power system?

Purchasing a solar power system is an investment and needs to be treated as such. The initial investment can be rather large depending on the over all power production of the solar power system. However, many states and the federal government offer rebates, tax credits and other incentives to reduce the overall cost of a solar powered system. Over time solar powered system will save you money in the long run because energy production from the sun is practically without cost.
How is solar power affected by fossil fuel prices?

Because solar power’s fuel is sun light you will not be affected by fluctuating oil and natural gas prices. With a solar electric production system your cost per kilowatt is fixed to the installation cost. Once your solar power system has generated enough electricity to recoup the initial investment cost it is then producing free electricity. As oil and natural gas prices climb so to does the cost of electricity from the utility company, which means that the utility company will pay you even more for the excess electricity produced by your solar power system.
Many people weigh the advantages and disadvantages of solar power before opting to buy a solar power system. However, some home owners instantly find the eco-friendly benefits of solar power to be enough to convince them to purchase a solar powered system. Because solar energy is clean, sustainable and renewable, you are helping to preserve the environment by preventing air pollution from nitrogen oxide, carbon dioxide, mercury or sulphur dioxide – the common by products of burning oil, coal and natural gas.
What are the Negative Aspects of Solar Power?

While some sources focus on the advantages that a solar power system can provide you, it is important to understand both advantages and disadvantages of solar power to ensure that you are ready to face financial responsibilities, legalities and other issues associated with mounting a solar panel on your rooftop. The largest disadvantage of solar power is the initial cost of installing the system. Since the materials used in building a solar power system are quality and high-cost components, one solar power system can be equivalent to paying a few years of electricity bills. While financial options are available, not everyone can afford the initial investment compared to purchasing electricity from their utility company.
You are not guaranteed to receive constant power. After the sun sets, your energy source is completely gone until the sun rises again the following day. This problem can be reduced by installing a battery bank and storing some of the electricity produced during the day.
Insufficient amount of “southerly” facing surfaces to install the solar panels on. You must have a sufficient square foot area that is clear of obstructions, such as trees and other buildings, that receives a lot of sun exposure during the day.

Number of sunny days will affect the amount of solar power produced.
Other factors that can reduce the output from a solar power system are: air pollution, clouds, and fog.
Now that you know the advantages and disadvantages of solar power, you can now make an informed decision on whether your personal circumstances, location and needs can be met by a solar power system.
