FAQ

The ideal placement of a solar system is on a southern or western facing roof with minimal shading and lots of available roof space. Clean Solar looks for the optimal roof surfaces of each home, which is why we like to get on the roof during our onsite appointments.

Adding a solar system to your home can potentially increase the resale value of your home. In 2014, Lawrence Berkeley National Laboratory conducted a study that showed buyers are willing to pay a premium of $12,000 to $15,000 for a home with an average sized resident owned solar system.  

Your savings depends on how much of your monthly bill is able to be offset and how large of a system you are able to install on your roof. If your average utility bill is currently $200, you may save up to $180 a month.

Yes, shade is the enemy to solar. Shading on your solar system prohibits the maximum energy production of each panel affected by shade. Your system can produce energy with roof shading but the production will lessen as sunlight is not on parts of your roof. Microinverters and optimizers help maximize energy production even when shade is present.

The project timeline for your solar installation begins with your Clean Solar contract signing and is completed when your utility company has given you Permission to Operate (PTO). This will take approximately 6-10 weeks on average. Throughout this process, Clean Solar takes care of all the design, permit and installation plans of your solar system. The actual installation of your solar system is 1-3 days. Find out more…

An inverter changes the DC energy produced by your solar panels to AC energy that is ready to be used in your home and on the grid. We offer microinverters and single inverters with optimizers for residential installations. The best option for your home will depend on the placement and size of your solar system.

The 30% Federal Investment Tax Credit is still available through December 31, 2019, with no maximum credit amount. This credit is scheduled to decrease to 26% in 2020, 22% in 2021 and then 0% in 2022.

During the day when your solar system is producing more energy than your household can use, the excess energy can go towards charging your battery. Later in the day, when your solar is not producing as much energy and rates are higher, the energy that was stored in your battery can be used for your daily tasks at $0 charge to you! This allows for you to get more out of your solar system and offset higher PG&E rates.

The battery will sense the power outage and automatically transition into backup mode.  It will be wired to an essential load panel, in which you select the rooms and appliances that are critical to your family. In the case of a long power outage, your solar system can refill the power in your battery.

Clean Solar installs grid tied residential solar and battery systems, meaning that you can retrieve energy from the grid when your solar system and battery are not providing enough energy to power your house. We do not install off grid solar systems.
