Solar FAQ’s
Why should I install a Solar PV system now?
- Solar is now cost-effective compared to utility grid electricity
- To eliminate or reduce your electric bill
- To turn your variable energy cost into a fixed cost for decades to come.
- Solar increases the value of property.
- To utilize current incentives such as California Solar Initiative Rebates and Federal Tax Incentives for solar.
- Adds significant value to your property without increasing property taxes
- Become energy independent for the future.
- Do the right thing for the environment and yourself.
How does a Solar PV system work?
The system converts sunlight into electricity through the Photovoltaic process. The panels on the roof react when exposed to sunlight by creating DC (direct current) which is sent to the Inverter and 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 SunWize 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 can not be paid for net negative annual usage.
How much does a photovoltaic system cost?
- 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 range from a low of about $15,000 to well over $1,000,000 for large commercial projects and typically pay for themselves in less than 10 years. Depending on the situation it can be closer to 5 years
- The customer has to look at 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.
- They don’t cost anything! They pay for themselves using financing
Do I need batteries to back up the system?
No. A SunWize 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 SunWize 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 / 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 SunWize 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?
SunWize 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! 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 SunWize 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. SunWize Systems is an experienced, licensed and bonded California contractor, with hundreds of completed installations.
Who takes care of city building permits? HOA applications?
SunWize Technologies 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 carry a 10 year warranty.
What if the system is not functioning properly?
SunWize 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. Call us as soon as you believe there is a problem.
How much energy is used in the manufacture of a photovoltaic system?
Photovoltaic installations have a positive energy balance. The energy used in the manufacture of a solar installation is paid back after approximately three to five years, depending on the quality, design and manufacturer. With an average service life of 20 to 25 years – which is guaranteed by the manufacturers – the energy balance is clearly a positive one.
How environmentally friendly is the manufacturing process?
The environmental impact and safety risk associated with the manufacture 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 manufacture of solar cells today is completely harmless.
Do I need to notify my building insurance provider when I install a system?
Yes. Because the 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 contractors 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 like SunWize that does the job quickly and economically.
What is the process to buy a PV System?
- 12 months of electric usage is first analyzed, and the extent of your desire to be energy independent is discussed.
- A site survey is completed by a trained SunWize solar specialist. Special attention is paid to roof materials, roof pitch or slope, sun orientation and shading, plus aesthetic concerns.
- Next we design a custom system just for you.
- After your approval and contracts are completed, a deposit is accepted.
- Then the necessary documents are prepared and submitted to reserve the rebates, receive city permit approval and begin the job.
