Traditional solar cells based on silicon semiconductor compounds have a theoretical maximum efficiency of 29% in converting sunlight into electrical energy.

An off-grid solar system is a solar power system that is not connected to the electrical grid. This means that the system must generate and store all of the electricity that it needs to operate.

Solar power is a great way to save money on your electricity bill and reduce your carbon footprint. If you're thinking about installing solar panels on your home, there are a few things you need to do to select the right system for your needs.
