Installation effectively combines three high risk industries in one: roofing, carpentry, and electrical work. [2] There is a risk of electrocution from installation or nearby power lines, [10] as well as ergonomic risks from heavy loads or a lack of lifting equipment. Cold or heat stress and sun exposure can also occur. [11] Solar Farm
PV panels mounted on roof Workers install residential rooftop solar panels. The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
As of May 2017, installation of a rooftop solar system costs an average of $20,000. In the past, it had been more expensive. [15] Utility Dive wrote, "For most people, adding a solar system on top of other bills and priorities is a luxury" and "rooftop solar companies by and large cater to the wealthier portions of the American population."

According to energyinfomative.org, the average cost for a residential solar system is between $15,000 and $40,000 (USD), and about $7 per watt. [11] In the article, it says that at today's rates, it would take 10 years to pay off an average system. As a solar panel may last more than 20 years, [12] in the end, it becomes a benefit.
In an indirect-gain passive solar system, the thermal mass (concrete, masonry, or water) is located directly behind the south-facing glass and in front of the heated indoor space and so there is no direct heating. The position of the mass prevents sunlight from entering the indoor space and can also obstruct the view through the glass.
