I hope this email finds you very well.
We have the intention to set a lab for evaluating and testing solar system components (especially panels or modules) in terms of efficiency, power, current, voltage and other parameters.
So, we would be grateful and thankful, if you can provide us with an offer containing the types and characteristics of instruments and devices that are used for evaluating solar systems (wether outdoor or indoor test(laboratory devices)) and their prices.
best regards
