Price & What You Get
Though it retails for a very reasonable price over just $200, many DIY enthusiasts want to buy the solar panel without the controller that it comes with. Unfortunately, the company has made this product available only in a combination offer where they will ship it with the 20 A PWM controller with 10 feet of wiring. If you are one such person not wanting the charge controller and just want the panels, we highly recommend that you buy the panel with the charger as the charger provides you with excellent energy efficient optimization. This is particularly true if you live in an area where the temperature drops rather significantly through the day, even while sunlight is around.
Not a lot of people know that changes in temperature can rather acutely affect solar power performance. Having a charge controller will negate that drop in efficiency. With an easy to read LCD display, the charge controller also protects your panels and batteries against over-charging, over-discharging and short circuits. It will also give you options like a boost charge option, to help you harness as much solar energy as you can in a period of 2 hours, with just a bit of programming on the charge controller.
As for the manufacturer HQST, it is an up and coming company with a strong presence in the solar panel field. Their products are competitively priced and designed with engineered features that you usually only see in much higher priced solar panels. HQST makes over 100 solar energy products and thousands of accessories and are an active OEM manufacturer to companies as well, catering to solar projects all over the world. You can be rest assured that you are buying from a reliable brand when you buy this HQST portable solar charger.
