Hi,

I have already a renogy 100watts if I purchase a grape, can they work in parallel?

thanks for the advice experts!

Based on the Vmp & Imp technical data for each panel they are really both rated 100 watts so essential the same and should work in parallel.

It would work but why would you use 12 volt battery panels? Just buy a single 200 watt Grid Tied panel and a MPPT controller to save a lot of money.

I agree with Sunking.

Sell the 100 watt Renogy panel and purchase a 200 watt grid tie. You will be saving money even if you sell the Renogy panel for a slight loss.

Sunking / SunEagle, thanks for the suggestion, any website link to good panels like the one you are recommending?

Those 100watts are cheap I think. Just looking for experts advice and best saving money options.

I do not have links, but many members do for $1/watt GT panels. a 200 watt GT panel with MPPT controller will cost roughly $400, and does the work of 300 watt battery panels with PWM costing $600.
