I had been toying with the idea of installing a roof top solar plant for more than a year and had contacted multiple installers, but I was not very satisfied with any of them. After I saw a few of Sunil’s many YouTube videos, I knew that Hinren Technologies would be my choice. Subsequently I contacted Sunil and found that his working style, knowledge and attitude ticked all the right boxes for me. I found Sunil to be very knowledgeable and transparent in his dealings. I was particularly impressed by his attention to detail, a trait which seems to be lacking in most people these days. Sunil and his team installed our system very professionally, keeping in mind even the minutest of details and commissioned it well within the timeline. I would wholeheartedly recommend Hinren Technologies to anyone looking for a professional installer and wish Sunil and his team all the very best.
Extremely professional work. Sunil and his staff ensured a seamless job with everything well planned and executed with minimal inconvenience and disruption. The entire process, from explaining the options, the material to go with, the plan for execution was well explained and documented. Highly recommend Hinren and Sunil.
It's been 3.5 years since we installed our On-grid Rooftop Solar System thru Hinren Engineering. Found Mr Sunil Mysore of Hinren to be very knowledgeable and professional during the entire setup & installation process. What I would like to highlight is the concern and unwavering Customer Support even after 3.5 years of installation. A very highly commendable trait. Thank you Sunil & All the very Best.
Working with Sunil and his team was an excellent experience. We changed the position of the solar system during construction, and his team was supportive during the entire process. For the new position (adjacent to the main entrance to our 1,900 sq ft house) Sunil designed the layout to ensure it is visually neat and all units are aligned and the wiring is neatly done. Today the solar system is the first thing one sees after entering the house! I look forward to working with Sunil and his team again, soon.
Mr. Sunil Mysore is an easy-going and very tolerant individual. He possesses extensive knowledge and demonstrates true professionalism. His belief in the concept of green energy extends beyond mere business interests; it is a genuine commitment. Mr. Sunil consistently delivers on promises, often exceeding expectations. He takes a personal interest in projects from the planning stages through to execution, showing a high level of receptiveness to suggestions and accommodating clients' needs. His team mirrors his professionalism—they are systematic, non-intrusive, and ensure thorough clean-up after completing their work.
Our Ashrama, Ramakrishna Yogashrama, is located a little outside Bengaluru. I have known Mr. Sunil and the Hinren Engineering team for almost 8 years now, and I can confidently say they are one of the most passionate and committed teams I have ever met. In 2019, they installed multiple solar systems in our Ashrama, and in 2025, we upgraded all of them with their help. This upgrade included the addition of AC batteries and a completely new solar PV system. For our student stay area and Goshala, we upgraded to LFP batteries and installed new panels. Every system was installed with the best quality materials and to the highest professional standards. Mr. Sunil personally took a deep interest in our projects and supervised almost every stage of the work. The quality of the installations speaks for itself — with meticulous attention to detail, uncompromising safety measures, and excellent aesthetics. Our Ashrama houses about 40 students, along with staff members and visiting devotees. For a long time, we had a serious challenge with cooking gas — there was a cap on the number of LPG cylinders we could procure, and the rising costs along with frequent shortages made the situation worrisome. At this juncture, Mr. Sunil suggested setting up a biogas digester on our campus. He proposed using cow dung from our Desi Goshala and organic kitchen waste to generate clean cooking gas. Following his advice, we installed a fixed dome biogas digester — ideal for our higher feed volume and pressure requirements. As always, the project was executed professionally, with an eye for every minute detail. Today, we generate enough biogas to meet our cooking needs for about 4 hours daily. In addition, the system produces nearly 50 litres of rich liquid fertilizer every day, which we dilute with water and use on our farms. This has completely eliminated our need to purchase manure or chemical fertilizers. Thanks to Hinren Engineering’s expertise, both our solar and biogas systems are designed and executed to perfection, combining sustainability with practicality. We sincerely appreciate and congratulate the Hinren Engineering team, led with great passion by Sri Sunil, for their outstanding work. Our Ashrama now stands as a living example of not only sustainability but also responsibility. We wholeheartedly wish them the very best in their journey towards a greener future.
I was looking for a high quality, reliable and knowledgeable firm for fixing solar panels and batteries. I searched for over an year and found Hinren. They fit the bill for high quality and reliability.
After returning from the US, I was eager to embrace sustainable energy solutions. While my initial search with friends and relatives didn't yield many promising options, I stumbled upon Hinren Engineering Solutions. Mr. Sunil Mysore and his team have truly exceeded expectations in installing a grid-tied solar power system for our home this October. From the initial consultation to the final grid connection with BESCOM, Mr. Sunil's transparency and meticulous attention to detail were commendable. His team's professionalism and efficiency were evident throughout the installation process, ensuring a neat and timely completion. I'm particularly impressed with the innovative use of space under the solar panels. The potential for creating a serene outdoor area with plants and seating is a fantastic addition to our home. I wholeheartedly recommend Hinren Engineering for anyone seeking a reliable and efficient solar power solution. Thank you, Mr. Sunil and team, for a job well done!
Rooftop solar system: Hinren Engineering helped us install on-grid system where solar power produced is interfaced with the power utility grid. They did a pretty decent job and we are reaping the full benefit of this installation. Through the Enlighten App , we are able to monitor the energy parameters. Appreciate the Good Customer Service and Support from Mr. Sunil Rainwater harvesting system: We got the RainWater Harvesting about 10 year back (2012) via Sunil , Hinren Engineering. We got this done after our house construction , so we were worried , if the aesthetics of the house would get impacted, But Mr.Sunil did a pretty decent job without much impacting to the aesthetics. His design was pretty unique aiming at minimum wastage of rainwater. A small filter is constructed. The filtered water recharges the borewell and then the sump and then to underground bed to recharge the ground water. Even though all our neighbour's Borewells have dried up. Since the rainwater was implemented , our borewell is totally recharged. Also during raining days , we hardly use the BWSSB supplied water. Infact we had water source at about 450 Ft below. Due to the recharge , the water is available at 50 ft itself. The whole system is working fit and fine with minimum maintenance Glad we installed this in our home.
It was a great experience to have an expert like Mr Sunil of HINREN ENGINEERING to plan and execute a ground water recharge well for my house. His team were extremely punctual and meticulous in execution.
Mr Sunil, Hinren Engineering Pvt Ltd, creates an everlasting experience with his clients. His passion for renewable energy sources reflects in his knowledge and commitment towards his installations. Clear site evaluation, user requirements understanding, clear advice to clients, well defined scope of work, use of superior quality products, workmanship and neatness in execution of work by him and his team are noteworthy and experiences to learn from. Meticulous follow up, till the customer is well educated on the parameters and aspects of the system. Thoroughly enjoyed the journey of off-grid installation. Given the location, he also helped my family to transition into solar cooking, by installing a solar cooker at home.
Mr Sunil and team exhibited high levels of agility and very sound technical abilities. We thank them for the flawless and hassle free execution of the project.Great work
