Solar panels are usually good on homes and roofs.

Solar panels are usually good on homes and roofs.
only single-family homes with a southern facing rooftop could get solar panels, but thanks to an improvement in efficiency of the panels and an acceptance of solar in general, now people in condos, townhomes, and even whole communities can enjoy solar.

Solar panels are still quite useful if installed on roofs that face east, west, north, and south. Often where there is not a south-facing roof, a house will have both east and west facing roof spaces.

Time of use billing basically means that the more that people use power from the utilities, the more it will cost. This is particularly the case in California where all residential customers will be on time of use billing plans from their utility by the end of 2019. If you use solar panels during the day and use the grid at night when it is less expensive, you will be using time of use billing to your advantage. Power in the middle of the day or middle of the night will be less expensive than power from 5 pm to 9 pm.

Information about solar panels in the shade


Shade will affect the number of kWh (kilowatt hours) of electricity that home solar panel systems would produce, but modern solar installers can work around these issues and find the setup.

Prior to 2011, it was the case that a small amount of shading would make solar panels not viable for a home. The reason for this is that solar panels were connected electrically in a series (often known as a string), almost like Christmas lights are all connected together with one wire. 

In this configuration, the amperage that can come from each panel is only as much as the amps that flow through the panel with the lowest amount of current. It’s like the sports adage, you are only as good as your weakest link. If one panel is shaded it would lower the output all the panels in the string.

Once
microinverters were created rooftop solar panels became easier 
 

What this means is that a reduction in Amps in one panel caused by shade no longer affects the other panels that are not in shade. Microinverters optimize the energy at each panel level by diverse current (I) and voltage (V) to maximize power output and then changing it to AC power at the panel. However, since 2011 micro-inverters and panel level optimizers have become quite common and have taken a meaningful serving of the market serving ways from series-inverters.
