Frequently Asked Questions
Financial
We offer monthly and prepaid PPAs through the SolarWorld Freedom Plan. Our finance team can also provide details about attractive solar loans in case you want to own the system on your roof but would prefer low money down. Please ask our sales team about the latest finance options available. No matter which financing option you choose, your new total monthly payments will be generating financial return vs. simply paying the utility monies that do not generate financial return.
There are other local incentives that you may qualify for. New homes automatically qualify for the New Solar Homes Partnership program rebates and many fully remodeled homes also qualify for this excellent incentive. We’ll make the effort to ensure that your project will qualify for all possible incentives available.
This comes down to the quality of the panels. SolarWorld panels have been proven to last over 30 years. Panels that are not quality made will fail well before this; typically after 12 years or so. Here are some tips:
- Look for performance history; how long has the company been making panels for? Do not blindly trust 25 year warranties from companies that have been around for less than 5 years.
- Where were the panels made? In the USA? Do you know where the factory is? Many companies claim to have panels “Made in the USA” when they are in fact made in Asia and only assembled here in the U.S..
Guide
There are two common solar technologies on rooftops today: solar thermal and solar photovoltaic (PV).Solar thermal is basically a very long black pipe coil that circulates water. As the sun rays hit the black piping, the water heats up. This water can then be used for your pool or stored in your water tank.
Solar PV consists of panels that turn the sun rays into electricity. The electricity generated can be used for any number of purposes (heating, cooling, powering electronics…). Because there are no moving parts there is very little maintenance.
If it is cloudy your solar system will not be producing electricity at its maximum capacity. But you would be surprised how much electricity can still be generated. Germany has the highest production of residential solar in the world, and they have far less sunshine than sunny California!At night, you shouldn’t expect any production from your system. (Although some full moons are bright enough to generate some electricity!)
Because your home remains connected to the electric grid, even if your system is not generating electricity, you will always have power. So there is no need to worry about being left in the dark.
Installation
Batteries are typically only used for off-grid buildings.

Irradiance refers to the power of solar radiation per unit area on a surface. Global irradiance on a horizontal surface is comprised of direct irradiance and diffuse irradiance. On a tilted surface, the reflected irradiance from the ground also contributes to the total global irradiance. Generally, solar irradiance is called insolation.
Solar radiation affects many systems in the house and can vary considerably within the same town. On-site, solar irradiance is a particularly useful measurement if there is a photovoltaic (PV) system or solar thermal system installed at the field test location. Also, if space conditioning is a focus of the field test, solar irradiance is an important measurement as solar radiation has a large effect on heating and cooling load requirements, electrical lighting demand (daylighting), and envelope performance.
