The cost for this unit is not cheap. For the same amount of gas, you could purchase a larger, tankless model that is solar powered. The only problem with this unit is that it does not provide you with any electrical power during the hot summer months. When it gets hot outside, you will find that your solar panels are going to be very hot and it is not going to be comfortable to operate in those conditions.
On the other hand, a condensing unit that is powered by the sun will continue to provide you with power as long as there is no major storm. This unit is also a little bit quieter than the other models of this type of unit. The only drawback to using this unit is that the condensing unit does not really offer you with any warranties. If you think that you can’t live without the electricity that the battery charger offers, then this would be the perfect option for you.
Although it is a small price to pay, it is one that you will definitely want to keep in mind when you compare the two types of units that are available. A lot of people tend to overlook the fact that they do not get anything for nothing when it comes to making the decision of purchasing these products. Take the time to research on the internet and find out all that you can about the product before you purchase it.
