Rob Perks
Solar Consultant
30 years an environmental advocate. Now he does it one roof at a time.
Rob Perks spent more than three decades in environmental advocacy before concluding that some of the most meaningful climate action happens where people actually live. What advocacy taught him was how to explain a complicated thing plainly and let someone make their own decision. That is what a consultation with him is.
“Sustainability doesn't require sacrifice. In many cases the greener choice is also the smarter financial choice.”Talk to Rob
How it works
No pressure and no call centre. You talk to the person who will handle your project from the first question to the day the panels go up.

No upfront cost, with your choice of a 25-year or 5-year rate lock. Full maintenance included for the life of the program, and buyout or early prepayment available.
Purchase
Own the system outright for the strongest long-term return, with the full manufacturer and workmanship warranties behind it.
Battery storage
Keep the lights on through an outage and store what your roof makes during the day for use after dark.
Live monitoring
See what your system is producing in real time, so a problem surfaces as a number rather than as a surprise bill.

Questions people ask first
Is there still a 30% federal tax credit for solar?
Not for a new home system. The federal residential solar credit ended for systems completed after December 31, 2025, so anyone still advertising it for an install today is out of date. Rob will walk you through what does apply to your home, including any state programs, on the call.
What does "no upfront cost" actually mean?
With Solar Energy World's Savings+ program you do not pay for the equipment up front. You pay a monthly rate instead, which you can lock for 25 years or 5 years, and maintenance is included. Buyout and early prepayment are available. You will see the exact terms for your home before you decide anything.
How do I know whether my roof will work?
Direction, shading and the age of the roof all matter. They are checked as part of the free estimate, and if your roof is not a good fit you will be told so plainly.
Is this a sales call?
It is a consultation. Rob explains your options and the numbers, and you decide in your own time. There is no obligation and no cost for the estimate.
What should I have ready?
A recent electric bill. The usage on it is what sizes the system, so it makes the estimate far more accurate.
Where do you work?
Mainly Washington DC and Maryland. Solar Energy World also installs in Virginia, Delaware, Pennsylvania, New Jersey and Florida. Enter your ZIP code above and we will tell you what is available where you live.
