Q : What are the 3 types of solar power systems? A : The three types of solar power systems are grid-tied, off-grid, and hybrid. Grid Tied system: without battery backup but with the function of selling surplus electricity back to the grid. If the grid fails, the system cannot function, and if you don't need a battery and don't want to sell electricity back to the grid, you can install a smart meter to prevent the electricity from flowing back into the grid. Off-grid system: with battery backup, but without the function of selling surplus power back to the grid, can function in the event of a grid failure. Hybrid system: with battery backup, but also with the function of selling excess electricity back to the grid and a backup load that works in the event of a grid failure.
Q : What size solar system do I need to run my house? A : The size of the system is determined on the basis of your monthly electricity consumption and your household load. You can provide us with this data and we will configure it.
Q : How much does a 10 kW solar system produce? A : Usually this needs to be calculated based on your local peak sunshine time. For example, if you are in Germany, then the local average peak sunshine time is 4 hours, then the electricity that can be generated every day is 10kw*4h=40kwh.
Q : What roof types are Sunpal solar modules suitable for? A : Sunpal solar modules are suitable for a wide range of roof types, including pitched roofs, flat roofs, metal roofs and tile roofs, etc. To guarantee a safe and efficient solar installation, Sunpal conducts a thorough roof survey and assessment for each project.
