If your electricity bill is a major cost, solar probably helps.
EPC, PPA or hybrid — we recommend the fit

Highest long-term return. CAPEX required. Best when you have capital and want maximum savings.

Questions before you send your bill
What do you need from me to start?
A recent electricity bill (photo or PDF) and your location. Roof size, daytime usage pattern and any existing quote help us be more accurate, but are optional for the first estimate.
Is this really free?
Yes. The initial bill review and savings estimate are free and carry no obligation. A detailed proposal follows only if you want to move to a site survey.
EPC or PPA — which is better?
EPC (you own the system) usually gives the highest long-term return but needs CAPEX. A PPA needs no upfront capital — you pay a discounted rate for the solar power. We recommend the fit after seeing your bill.
How fast can a project move?
Typically: bill review in 48h, site survey within the first week, proposal in the second week, then engineering, PEA/MEA coordination and contract. Timelines depend on site and utility requirements.
Can you review a quote I already have?
Yes. Sending us your bill plus an existing EPC/PPA quote is one of the most valuable checks — we verify whether the sizing, assumptions and pricing match your real consumption.
