Solar Power and the Partially Shaded Roof

3 Mar

If you have a partially shaded roof and have tried to get a quote for a solar electric system youll know that the system that will be installed is much smaller than what you have the roof space for. California Green Designs is proud to announce that we can now work around your shading. The newest item in our product are micro-inverters. Microinverters are inverters that are attached individually to solar panels.

The reason why shading plays such a large row in solar electricity is due to the type of circuit solar panels are generally connected in. The way solar panels are initially attached in “series”  each series forms a “string”, and each string performs only as well as its weakest performer.

That is to say, when one panel is shaded, anywhere from 5 to 17 other panels lose production as well.

The  solar panels are attached in a dependent manner because of the inverter, (inverters change the type of electricity produced DC, to AC). The solution comes from changing the location and size of the inverter. Instead of one or two inverters for the entire system each panel is fitted with its own inverter. With this new found independence when one panel is shaded, it only effects the performance of that one panel..

The inverters are usually mounted just underneath the panels,Once the inverter are connected to the panels, the inverters are then connected to one another, and then AC energy flows through your solar meter and your electric grid. Any access energy goes back to the utility electric grid.

The new inverter is a product called the Enphase Microinverter, California Green Designs first started carrying the product earlier this year, and the first implementation just this month.

To read more about the new microinverter, and get a quote on what the system would cost for your home or business please fill out a form on our website or call us at 818 344 0440.
