Compare these two sources and perhaps more to determine if it's advantageous for a homeowner to install a battery to store excess power. What about for the community?
Now Elon Musk has created high-end roof shingles that have solar cells to make your entire roof solar and a home battery to store it all.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
These technologies convert sunlight directly into electricity to power homes and businesses.
These technologies harness heat from the sun to provide electricity for large power stations.
These technologies use solar energy to heat or cool commercial and industrial buildings.
