When lights shine on to the material, it knocks the electrons apart, which creates a flow of electricity. Although these cells don't need direct sunlight to generate electricity, since they can work on cloudy days, the stronger the beams from the sun, the more electricity will be generated.
Kilowatt-hours (kWh) is the actual electricity generated by solar panels, the same measurement as on your household electricity bill. But a 1kWp collection of panels will rarely (if ever) generate 1kW power. Most of the time the output will be lower.
The inverter will usually be placed in your loft, near the breaker panel, where it will take the DC power the panels supply and convert it into usable AC electricity. A cable will then take the electricity to your fuse board. There will also be an additional circuit breaker so you can control the flow of solar electricity.
Technically, yes, you can install solar panels on your own – but we strongly discourage you from doing so, unless you're a certified installer. You'll need expertise in roofing and electrical work, as well as specialist equipment and – in most cases – scaffolding.
