China is the largest supplier of solar panels in the world, and many top-tier brands manufacture their technology there. However, be aware that you get what you pay for. There are inferior quality panels offered on the market at suspiciously low prices. You may save $1,000 on the initial installation cost, but replacing cheap, failing panels will cost you many times that amount in the long run. We only install proven, high-quality components.

Because solar panels are designed to be up there for 20 to 30 years, if you have major issues with your roof, the answer is yes. If your roof is in decent condition, some minor maintenance before the install might be helpful, but it isn't strictly necessary. However, if you have tiles covered with mildew or heavy dirt, we highly recommend having the roof cleaned beforehand.

The power output of all solar panels naturally degrades over time. A solar panel performance warranty is a manufacturer's guarantee that only covers the performance of the panel in terms of power output and how much it degrades (it does not cover the physical panel as a product). The standard performance warranty is 25-years, guaranteeing that most panels will only degrade over 25 years to around 80% of their original output.

Keeping your solar panels clean is important for maintaining optimal performance. Since most residential solar panels are installed at an angle, rain naturally helps wash them clean. However, if you notice a build-up of bird droppings, dust, or dirty areas on the panels, it’s recommended to arrange a professional cleaning. Having the panels cleaned every few years helps maintain maximum efficiency, ensuring the high-quality panels installed by KTM Solar provide reliable, trouble-free performance for years to come.

Yes! Solar panels are a smart, long-term investment that pay for themselves over time through significant energy savings. Choosing a high-quality solar system from a trusted, licensed, and insured installation company like KTM Solar ensures reliable performance and years of trouble-free operation.

You don't have to have one, but it is highly recommended if you want to maximize your savings. Without a battery, your home uses solar power during the day, and any excess is sent back to the grid for a small credit. By adding a battery, you store that free daytime energy to power your home at night or during peak pricing periods, significantly reducing your reliance on the grid.

Yes, depending on how your system is configured. We can design and install battery systems with blackout protection capability. This means if the grid goes down, your battery will automatically take over, keeping your essential appliances—like your fridge, lights, and internet—running smoothly until the grid is restored.

Absolutely. If you already have solar panels installed, we can easily retrofit an AC-coupled battery system to work alongside your current setup. However, if you are looking to buy a new system from scratch, installing the panels and the battery at the same time is usually the most cost-effective approach.
