BrightSun at a glance
The team that outgrew a startup into a 22-person operation through word of mouth alone.
Lakshmi Narasimhan started BrightSun Solar as an Aerem partner in 2018 with four technicians and a site vehicle. Seven years and 310+ installations later, the company has 22 people -- five site engineers, twelve technicians, five operations -- and a waiting list for new installations in peak season.
That growth came entirely from one source: customers who had their expectations exceeded.
In an industry known for inflated generation estimates, BrightSun is the team that gives realistic numbers. Sridhar Rao from Indiranagar put it plainly: "I compared four installers. Lakshmi's team was the only one that gave me a realistic generation estimate instead of inflated numbers. They said 12-14 units/day for 3 kW -- and that is exactly what I am getting."
BrightSun's Platinum-tier certification reflects seven years of consistent 4.9/5 ratings, documented system performance, and zero outstanding warranty complaints.

What customers say
BrightSun is exceptional. We installed 8 kW for our 4BHK villa. The team spent a full day just on the roof survey -- checking angles, shade patterns, structural load. Our system generates 32-35 units on sunny days. Monthly bill dropped from Rs 9,500 to under Rs 1,500. Payback will be under 3 years.

I compared four installers before choosing BrightSun through Suryam. Lakshmi's team was the only one that gave me a realistic generation estimate instead of inflated numbers. They said 12-14 units/day for 3 kW -- and that is exactly what I am getting. Honest people in an industry full of overpromises.

We were BrightSun's first installation in Mysuru. Even so, the work was flawless. 5 kW system, completed in 2.5 days. BESCOM net meter took 18 days. Now saving Rs 4,600 a month. The Suryam monitoring app shows me generation down to the minute. Very satisfying to watch.

Why Bengaluru is one of India's best cities for solar -- if the installer knows BESCOM.
Bengaluru has excellent solar irradiance (4.5-5.5 kWh/m2/day) and a DISCOM -- BESCOM -- that offers the highest net metering export rate in India: Rs 3.82/unit for exported power. When your system generates more than you use, that surplus earns you more credit in Bengaluru than almost anywhere else.
The Karnataka state subsidy adds Rs 10,000 per consumer, on top of PM Surya Ghar's Rs 78,000.
A 3 kW system in Bengaluru saves Rs 2,500-3,100/month. A 5 kW system saves Rs 4,100-5,200/month. Payback: 3.4-4.3 years for 5 kW.
BrightSun understands BESCOM in detail -- the net metering application process, the Gruha Jyothi free electricity scheme implications, and the Karnataka state subsidy paperwork. 310+ installations worth of BESCOM experience.
For Bengaluru tech community residents -- engineers, researchers, startup founders -- who want data, transparency, and installers who give honest estimates: BrightSun is the answer.

Certifications and credentials
We were one of Aerem's first partners in 2018. Back then we had 4 technicians. Now we have 22. Aerem did not just give us leads -- they gave us training, certification, monitoring tools, and a brand we could co-market with. The Platinum badge on our trucks gets us customers even without Suryam.
