My husband just showed me…
My husband just showed me the electric bills from the last few months versus same time last year. It's crazy how much money we're saving. I can't say enough about Greenleaf, and how professional they are. I was finally able to get rid of that ugly tree too, thanks Greenleaf!!!

I’ll be honest, I spoke…
I'll be honest, I spoke with about six different companies when deciding that we wanted solar for our home. I'm sick of the increasing prices from PSE&G, and figured there is no better time than now. What made GreenLeaf stand out is they took the time to educate me, and make me understand details and things I hadn't even considered. We're now six months after the installation date and not one statement the Greenleaf team made hasn't come true. We're saving money, and that was my goal.

If you're shopping for Solar, do your due diligence, but make sure to call this company, you'll thank me later :D

Very happy with Greenleaf, I…
Very happy with Greenleaf, I had been in the market for solar and talked with quite a few different companies and Keith from Greenleaf was much more honest and communicative about all my options compared to the others. I always seemed like their priority and they were very quick with getting everything done with the project. Will be recommending them to anyone I know looking for solar.

I’m so happy my wife…
I’m so happy my wife and I took our time finding a solar company to work with. We spoke with four different companies, and then we met Seth at Greenleaf solar. Him and his team went out of their way to educate us, calm our fears, and on the day of install he showed up personally to make sure everything was going perfectly. We’re happy to save the money each month on our electric bill and have no hesitation recommending to anyone.
