What is your warranty policy?
Manufacturer warranty for PV panels:
* 5 years limited warranty for material and workmanship defects.
* 10 years limited warranty for minimum 90% of peak module power output performance.
* 25 years limited warranty for minimum 80% of peak module power output performance.
Why chose to install a Solar PV system now?
Solar PV systems are now cost-effective compared to utility grid electricity
Eliminate or reduce your electric bill
Turn your variable energy cost into a fixed cost for decades to come
Increase the value of your property without increasing property taxes
Utilize current incentives such as California Solar Initiative Rebates and Federal Tax Incentives for solar.
Energy independence for the future
Help protect the environment
How does a Solar PV system work?
By converting sunlight into electricity through the Photovoltaic process, panels placed on the roof react when exposed to sunlight by creating DC (direct current).  The DC is sent to the Inverter and is converted into AC (alternating current), then supplied to the electrical system for use in the home.
What size system do I need to install?
Based on the customer’s electricity needs and desire to be energy independent, a Solar representative will analyze the potential solar panel locations, available sunlight, shading and other factors to tailor a system to your specific application. The ultimate system size decision will be up to you.
Can I make money by selling power to other people?
No, you can reduce your bill down to almost zero, there are a few dollars that are billed to any customer just to be connected to the grid, but currently you cannot be paid for net negative annual usage.
What’s the cost of a photovoltaic system?
System cost depends on size, materials and labor to install.
In many cases the monthly costs to own a PV system can be less than the monthly utility expense.
Grid-connected PV systems are as low as $15,000 to well over $1,000,000 for large commercial projects and typically pay for themselves within 5-10 years.
The customer should research and compare many items including product quality, cost per kW hours delivered as well as the reputation of the installer and the quality of workmanship.
Do I need batteries to back up the system?
No. A Solar grid-connected system uses the local utility grid like a big battery. On sunny days your excess power is fed into the grid giving you credit for future use. At night the power you draw from the utility is balanced against your credits. However, if the customer desires we can install a battery backup system for an additional cost.
How much will I save on my utility bill?
Ideally your Solar system will be designed to eliminate your electric bill. Restrictions however, on budget, space or sunlight exposure will affect savings potential.
What about Rebates or Financial Incentives?
The California Solar Initiative CSI program rebates start at $ 2.50 per watt or $ 2,500 per kW.
The Federal Investment Tax Credit for solar systems is 30% of the net cost, capped at $ 2,000 for residential systems.
The IRS allows for a 5 year Accelerated Depreciation Schedule for commercial solar systems.
Solar systems add to the value of a home but are exempt from California property tax.
Is financing available?
Yes! Many customers choose the Solar Residential Finance Program.
Will a PV solar system protect me from blackouts?
A standard grid-connected solar system will not operate when the electric grid is down. Some customers elect to install a hybrid grid-connected/battery back-up solar system that will provide blackout protection for selected critical circuits. The additional cost of the battery back-up system should be weighed against the amount of time per year blackouts occur and the value of having selected circuits available during blackout periods.
Which direction does my available roof space need to face?
South, West and East are all good.
What will my system look like on my roof?
Solar PV systems are designed to minimally impact the aesthetics of your home. Panels are often recessed into roof tiles or mounted flush with the existing roof structure. Often the panels can be mounted away from the ‘street view’ of the home.
Can I add to my system if I choose to later?
Yes! The system is modular. You can add up to the load limits of your inverter, and inverters can be added as well.
Can my roof be repaired after the system is installed?
Yes, however it is a good idea to make any repairs or re-roof if needed prior to having a PV system installed. If a new roof is needed once the system is in place, Solar installer can temporarily disconnect, remove, and then reinstall the panels for an hourly rate.
What maintenance will I have to perform on the system?
Solar panels are solid-state and maintenance free. Occasionally rinsing off the panels is the only maintenance required. The inverter is virtually maintenance free.
Does a PV system have to meet local building code?
Yes. Your system must pass both local building and national electric code requirements. Your Solar installer is usually experienced, licensed and bonded California contractor, with hundreds of completed installations.
Who takes care of city building permits? HOA applications?
Solar installer takes care of all permits and assists with HOA approvals, all included in the original contract price.
How do I know if my system is producing electricity?
Your inverter will read out a lot of information, such as current output and accumulated total electricity generated. A green light will be on when the system is functioning properly. Inverters usually carry a 10-year warranty.
What if the system is not functioning properly?
Solar installers usually warrantees your system for 10 years from date of startup. Make sure you choose someone who you believe will be in business 10 years from now.
How environmentally friendly is the manufacturing process?
Environmental impact and safety risk associated with the manufacturing of solar cells is negligible compared with conventional energy sources such as coal, oil and nuclear power. Especially the silicon that is used almost exclusively in the manufacturing of solar cells today is completely harmless.
Do I need to notify my building insurance provider when I install a system?
Yes, building insurance policy would also have to replace the PV system in the event of it being damaged, you should notify your insurance company, so that it is included under your policy.
Can I install a PV system myself?
Possibly, if you have a high tolerance for the government paperwork process, a contractor license, electrical systems experience, are not afraid to put numerous holes in your roof and don’t mind receiving a 15% lower State Rebate. Like all specialized jobs, there are very good reasons to hire an experienced company that does the job quickly and economically.
