Why should you purchase a solar controller?
Do you use solar panels for generating electricity and for running your electronics at home or in the office? Have you ever wondered what would happen with your appliances on a severely hot, sunny day in this case? Well, the excess sunlight can overheat the solar batteries, and this may cause damage. To prevent this from happening, you need solar controllers. The best solar controllers would ensure that appropriate amount of electric power gets distributed to and from the solar batteries that power the various appliances in your home or office.
What are the things you should consider when buying a solar controller?
After going through thousands of solar controller reviews, we have summarized what you should consider when buying one for your home or office:
Check the basic requirements: Solar controllers are available in different sizes and shapes. In order to find the one most appropriate for your home or office, you will first need to identify the voltage and current generated from your solar battery. Then check out the two types of solar controllers: the Pulse-Width Modulation (PWM) controllers, and the Maximum Power Point Tracking (MPPT) controllers. Identifying the features of both these types will help you decide which one is suitable for your needs.
PWM controller specifications: The PWM solar controller adjusts the charging rate depending upon the level of the battery that you are using. This helps charge the battery to the optimum level. The strong point of these solar controllers is their durability—they can be used for years and are rather competitively priced. They are available in sizes up to 60 Amps.
MPPT controller specifications: The MPPT solar controller costs more than the PWM controller, but it will work in a way so as to capture the maximum power from solar panels or cells. Since it can absorb a much higher amount of power, this type of solar controller is considered to be more efficient than PWM controllers. It has the capacity to retain a higher input voltage before converting it into electrical power.
Think of the last time you bought something you really cared about. Maybe it was a life insurance policy. Maybe it was a coffee pot. Some people really care about lip balm.
Think of the amount of Googling you did, the types of people and publications you turned to for advice, until you were confident you were buying the best thing for you.

From heated blankets to trampolines to cordless drills, we compare the top products in thousands of categories to give you the most reliable purchasing advice. Our goal is to make it easy for you to pick the best product and be confident in your decision.
Why trust Best-Reviews
Best-Reviews spends thousands of hours researching, analyzing, and testing products to recommend the best picks for most consumers. We only make money if you purchase a product through our links, and we never accept free products from manufacturers.
How Do We Work
We’ve assembled a team of researchers and reviewers who each bring specialized skills and expertise. (And this team is, of course, how we’re able to review so many products!). Our testing methodology looks something like this:
We send our Research Team out into the marketplace (i.e., the places you shop). They participate in online forums, monitor trends, follow industry news, rub elbows with thought leaders and keep an eye on new advancements in home and technology.
Our Editorial Team picks apart the data they gather to identify products and services of note. Their selections are based on a number of factors, including cost, availability, popularity, etc. Sometimes they’ll suggest a few dozen products for review; sometimes more.
When the final list is complete, our reviewers reach out to manufacturers in search of no-strings-attached samples or products available on loan. Side note: Most manufactures are happy to provide samples – never mind the possibility of a bad review – because they believe in the quality of their products and look forward to the free press – good, or bad. In some instances, when a product sample is not available, we head to the store and shell out the cash to pick it up just like you would.
With products in hand, our reviewers begin the meticulous review process, which includes using most products just as you would. This ensures we’re able to identify and communicate each product’s strengths and weaknesses in a way that makes sense to you.
Among other things, our tests gather data on features, ease of use, durability and the level of customer support provided by the manufacturer. Using a proprietary weighted system (i.e., a complicated algorithm), the data is scored and the rankings laid out, and we award the three top-ranked products with our Gold, Silver and Bronze Awards.
We then lay out each product grouping in a side-by-side comparison that’s unique to Best-Reviews Guide. Of course you can click on each product for a more in-depth look into what sets it apart from the others.
We also keep our reviews updated
A review may look simple and straightforward, but there’s a good chance it took over a month to complete. Something more complex? Try several. That’s because a good review is never finished. We continue to research, keeping our content updated by reviewing new products or making changes based on things like product recalls and emerging trends.
Our business hinges on credibility, and how useful each review is to you. We promise to tell the story of what we’ve found in a way that’s worth your time, so you can get what you need and get on with your day.
