Passive Solar Energy

It is a well known fact that the sun’s light and heat is strongest from a southern direction. This may not always be true because it depends in large part to where you live. However, if you want to build a solar powered home consider this fact. You can maximize the sun’s potential passively and conserve energy too by implementing this knowledge in your house construction.

Passive solar technology uses heat from the sun naturally, just as it is. There is no mechanism used to capture the sun’s energy and convert it into electricity like an active solar system. Natural heat from the sun can be used for several things. It offers direct and indirect use for heating spaces, heating water systems and to regulate indoor temperatures with the use of thermal mass materials. You can heat homes and businesses with passive solar.

Sun rooms are an example of passive solar power as it lets the sun come into a room without allowing it to escape. Heat can be retained in a room by the glass used for windows and by the materials in the room. Certain materials absorb and retain heat better than others.

A solar furnace is another example of passive solar power. A solar furnace is a structure that uses concentrated solar power to produce high temperatures, usually for industry. Of course, modifications can be made to this concept for home use. A solar furnace is any huge object that is created in order to channel the heat directly to one place. Parabolic mirrors or heliostats concentrate light onto a focal point, just like how a magnifying glass works. The temperature at the focal point may reach 3,500 degrees celsius or 6, 330 degrees fahrenheit, super hot.

Solar gain is referring to the increase in temperature in an area, an object or a structure that is a result of solar radiation. The stronger the sun the more solar gain you have. The cost of passive solar compared with active solar is significantly less making it more affordable. An active solar system has a lot more parts. Remember, active solar systems gather and capture energy from the sun and then convert that energy into electricity.

Passive solar power can be a good place to start using the sun’s energy because it is less expensive and you can see if you like solar power or not. You will know if you want to upgrade to active solar power with a safe passive solar experiment.


Passive solar power is something that we will be seeing a lot of in the future as the need for solar power becomes more in demand. The optimal solution for your solar powered home is to implement both passive and active solar power into your energy savings plan.

Installations done right

Our philosphy is to only use the highest quality equipment on the market.   Every panel we sell comes with a 25 year warranty and we back that with our 25 year labor warranty which gives you peace of mind knowing your solar system will be supplying your home energy well into the future.

I have never dealt with a business so customer orientated and honest. I’ve had my system installed for 3 months now and am very happy with workmanship and final outcome. They were super professional and attentive during the install and went above and beyond the call of duty. I highly recommend SPBB for any solar and electrical job. Thank you again.  A+
