my dad wants to run all his lights in his shop on solar panels, he has 9 600 watt hps lights. how many solar panels would it take to pull this off
If he lives in a sunny area, he should contact a local solar installer about getting a grid-tied solar system to offset his electric bill. It's not necessary to supply all the electricity from solar. The system will work seamlessly right alongside grid electricity, and your father can choose whether to supply 20% of the electricity or 99% by sizing the system appropriately.
It depends on how many watts of electricity you wants..
dozens at a huge cost which only run in sunlight so not ideal for running lights, solar panels are just not economical or reliable, probably around $5000?
