Successful Project


Energize Your Business: Maria’s 250W Solar Success Unveiled

This was a very exciting project we did a few months ago.

Mrs. Maria is a businesswoman in Madrid, Spain. She has been reading a lot of our successful projects from our customers. And this spiked her interest. Since she was struggling to keep her business a float with the rising electricity costs.

Maria said her electricity bill was up by a whopping more than 27%. We put her through our experts, who were set to end her problems. Once we understood how much energy she needed, it was all systems go.

We determined the right dimensions as per Maria’s roofing design. And took in all other factors that would affect the panel’s performance in Madrid. We agreed on 12 units of 250-watt panels and batteries. She also got a discount as our first-term buyer.

We shipped all the products in less than 2 weeks. They were installed, and she called to appreciate our panel’s quality. She’s no longer at the mercy of the grid! In fact, she says her business is now doing better than EVER.

From our feedback follow-up, Maria says she appreciates our professional customer service. Timely delivery. Pristine quality. And after-sales service.

You, too, can join Maria and enjoy an affordable & uninterrupted power supply!

What our CUSTOMERs say


Leeline Energy is the BEST when it comes to solar products. After countless disappointments from online stores. I gave Leeline a shot. I ordered 2 units of 250-watt solar panels. And these guys exceeded my expectations. From their timely responses to first deliveries. And the quality? 10/10 !!

Oliver Butler

My pal ordered a 250-watt panel from Leeline Energy, and he couldn’t keep calm. Had to order the same from them, and now I know why. The quality of their panels is fire!! Delivery was super-fast. And installation was pretty easy, too. I’ll definitely buy more solar products from them in the future.
