Solar Generation
On-site Generation
Commercial and industrial PV systems under distributed generation, designed, installed and maintained by us.
The costliest mistake
A system can generate as much energy over the year as you consume and still leave your demand charge untouched. The reason is the clock: the sun delivers at midday and your peak period starts after the sun has gone.
Illustrative curves. The conclusion is not: if your tariff charges for demand and your peak is in the evening, the optimal system size is not the one that covers your annual consumption — and that difference is worth money every month.




What sets us apart
Against your load profile and the real breakdown of your tariff, not against the bill total. That is where it is decided whether the system delivers the savings it promises or only part of them.
We verify that the roof can bear the load and handle the distributed generation interconnection filing from start to finish.
A system without maintenance loses generation silently, and the owner finds out when the bill stops going down. Every system we deliver comes with a proposed service contract.
Scope
About the numbers
Real savings depend on your tariff, your hourly profile, the available area and the orientation of your roof. We give you your plant's number, with your bill in hand, and we give it to you in writing before you sign anything.
Not an annual average: all twelve months, because your consumption is not flat either.
Off-peak, mid-peak and peak energy, and what happens to your demand charge.
Generation drops every year. If the proposal does not say so, the payback is inflated.
Questions
If your consumption is mainly at night, solar on its own will disappoint you. It is worth evaluating it together with storage, or not at all.
If your roof needs replacing in the next three years, do the roof first. Removing and reinstalling a system costs more than waiting.
