"Got 4 quotes. DE came in the middle on price but Miles actually walked me through the STC paperwork. Install was clean — 6 hours, no mess, panels perfectly aligned. First bill after solar: $28 credit."
"Old tile roof and they still got it done in a day. The guy even patched two cracked tiles he spotted without being asked. That kind of thing makes you trust a company."
"Honestly expected a sales pitch. Got a 20 minute roof assessment and a straightforward proposal. They told me I did NOT need the bigger inverter — saved me $1,200 by not overselling."
"Added the Sigenergy battery last month. The app shows we are 92% self-powered now. DE handled the battery rebate paperwork — $4,000 off. Whole thing took 2 days from quote to install."
"Our strata was a nightmare — 6 months of back and forth. DE's admin team handled every form. 8 apartments now sharing a 30kW system. Body corp fees dropped $180 per quarter."
"Had solar for 2 years before calling DE to add panels. The original installer ghosted us. DE found a loose MC4 connector from the original install — could have been a fire risk. Fixed it for free."
