Can I Go Solar?

Before you climb out on your roof with a measuring tape, pencil and notepad, review the following checklist:

	1. Do you have a southern oriented roof? In the Northern Hemisphere the sun crosses the horizon in southern orientation (see illustration.) Before purchasing a system, verify that you have available roof space facing south.
	2. Do you have sufficient roof space? Typically, you need 30-60 square feet of southern facing roof for your system.
	3. Do you live in a "warm" or "cold" climate? Solar thermal systems are divided into "warm" and "cold" climate systems. Determining your climate type will help you choose the most efficient system for your application. The following short climate descriptions will help you determine your climate type:

Cold Climate (Closed Loop System)
A region is considered a cold climate if it is prone to freezing temperatures in the winter. Cold climates require a closed loop system using a special antifreeze fluid to eliminate damage to pipes when the outside temperature drops below freezing. We also use evacuated tube collector panels for higher efficiency when the ambient temperature is significantly lower than the fluids return temperature.

Warm Climate (Open Loop System)
A region is considered a warm climate if it is not prone to freezing temperatures in the winter. A warm climate allows us to use an open loop system where water circulates through your collector into a boiler. The open loop system allows simpler and, therefore, lower cost system.
