This kit provides plenty of clean power for my home. The battery capacity is impressive, and the inverter runs everything smoothly. Easy to install and very reliable.
Installed this kit at my cabin and it works great. Plenty of power from the panels, and the batteries last through cloudy days. Setup was straightforward. Very happy with the performance!
I installed the SunGoldPower 450W panels on my home rooftop last month, and I’m really happy with the performance so far. The build quality feels solid and durable, and the monocrystalline cells are clearly efficient — I’ve noticed a significant boost in my energy output compared to my old setup. Installation was straightforward, and the customer support team was very helpful when I had questions. Highly recommend for anyone looking to upgrade their solar system!
I recently purchased a solar panel from Modern Homestead Co., and I am extremely satisfied with my decision! The installation process was straightforward, and the panel itself is high-quality and efficient. I’ve already noticed a significant reduction in my energy bills. What really impressed me was the customer support; they were knowledgeable and guided me through the entire process, answering all my questions with patience. Thank You Modern Homestead Co.!
I love my MrCool DIY Mini Split 5-Zone system! The 12K BTU air handlers look great and cool each room quickly. Installation was straightforward, and the quality of the components is impressive. Customer support was helpful when I had questions. This system has made my home so much more comfortable, and I highly recommend it to anyone seeking a reliable air conditioning solution!
I've had the MrCool Olympus Mini Split system installed for a few months now, and it has exceeded all my expectations. The 36K BTU capacity is perfect for my three-zone setup, and I love how each room can be controlled independently. The ductless ceiling cassette units are incredibly quiet, which is a huge plus for my family since we spend a lot of time at home. The energy efficiency is remarkable—I’ve noticed a significant drop in my energy bills since switching to this system. The installation process was smooth, and the customer support team was very helpful with any questions I had. If you're in the market for a reliable and efficient heating and cooling solution, I can't recommend the MrCool Olympus enough!

Used this greenhouse all winter in Minnesota and it held up beautifully. On sunny days we still hit 45-50°F inside while outside was 20°F. The base kit and anchor options are solid; just make sure your base is level. Great unit for all-season use.
We chose the 12×16 because we needed more space than 12×12 but couldn’t go full commercial. This Model delivers. The sliding doors are big enough for wheelbarrows and the space is wide enough for dual benches and still a walkway. Setup took about two weekends with help. Minor note: finish work isn’t as slick as premium commercial units — but for the price the value is outstanding.
A wide footprint that works well for multiple growing bays. The Summit 12×12 provides enough width for two full benches and still gives workspace. On hot days the twin-wall panels do heat up inside fast — make sure you have automatic vents or shade cloth ready. Very happy with the quality.
For anyone considering a large kit, the Elite 8×24 is one of the best out there. You need to plan your base and ancillary equipment carefully (heaters, shade, kits) but if you do, you end up with a huge, functional greenhouse. I'm very happy with mine.
We’ve just assembled the Elite 8×20 and are really impressed. The 10 mm twin-wall panels lock with a solid frame, the 42″ double-doors roll smooth as promised, and even in wind gusts up to 50 mph our structure stayed rock-steady. A solid investment for serious growing.
Extra Space, Better Heat Retention, Perfect Choice
Upgraded to the Elite 8×16 and the difference is huge. The added length gave us bench space for our seedlings and a dedicated storage zone. The 10 mm twin-wall panels perform amazingly in winter, on sunny days we hit 50 °F inside when it was 20 °F outside. The frame is extremely durable with zero flex. Highly recommend.
We bought one. Take some time to assemble, but we finally touch down. For value and quality, we were thoroughly impressed with its performance. Wife love it.
The greenhouse was delivered well. The construction was easy. Once you get it all up it's pretty sturdy. I do recommend the 12 ft since the 8ft is more so for hobbyist.
Perfect for weekend camping trips. It powered my laptop, phone, and even a mini fridge without any issues. The compact design and quick recharge time are big pluses.

I’ve got the batteries installed so far and everything is working great. Still need to set up the two new inverters, but the process has been smooth up to this point. Thank you for the quality products and support!
Rich Solar NOVA 12K PV Hybrid Inverter Solar Kit
George W.
The setup was very easy, and as soon as I connected my batteries to the controller and switched on the panels, everything worked perfectly. The team at Rich Solar was incredibly helpful throughout the process, making the experience smooth and stress-free. The panels deliver plenty of power, and I’m very impressed with the output. From here on out, I won’t be buying anything other than Rich Solar!
Rich Solar 400W-1600W RV & Camping Solar Kit
Carol T.
The work on my 1975 GMC Transmode project is moving along nicely! This morning, my son Cory Miller helped me complete the final installation of the 1200-watt solar panel system I purchased from Rich Solar. Everything came together just as planned, and the setup turned out exactly as designed. I’m very pleased with the results and excited to see this classic build powered by solar.

I recently set up my 60 Amp controller panel, and it’s been working great. The installation was straightforward, and the system runs smoothly with no issues so far. I’m very pleased with the quality and performance—it really adds confidence to my solar setup.
