How to choose a good use of solar energy
See brandAt present, there are more than 5 thousand brands of solar water heater industry, of which, a small family workshop type enterprises accounted for the majority of such enterprises weak competitiveness, the average life expectancy of enterprises, but only 1.5 years. Consumers choose products produced by such enterprises, often a few years later will become a three noes products, the interests of consumers can not be guaranteed. Therefore, consumers should choose in the country's high visibility of the big brands, big brands of solar water heaters not only reliable product quality, but also to provide consumers with long-term after-sales service protection.
