With more than 20 years experience in mechanical and electric design, McDonald Solar and Wind Inc., is your renewable energy source provider in Colorado Springs and the Front Range. We provide all aspects of design, engineering, installation and service for photovoltaic, thermal and wind energy systems. We consider your budget, lifestyle and needs when we draft a proposal.We design and install grid-tied systems from 1kw to 1mw, off grid systems for homes and wind systems from 500w to 10kw and beyond using reliable contractors. Our work is warrantied and guaranteed. We also design and install solar thermal systems for water and space heating. Our services include. • Engineering • Design • Installation• ServicingThere are many ways to collect solar energy, including thermal collectors, photovoltaic panels, and solar concentrators. Most residential and commercial applications where the user wants to supply a significant amount of his/her energy usage from the sun use photovoltaic panels to convert the sun's energy to electricity. These systems are less of an investment in initial cost and do a lot to reduce energy costs in a household.Solar Photovoltaic (PV) systems trace their origins back to the early days of the Space Program. Even further back than that, the origins of the first PV cell were derived from the development of the first transistor back in the late 40's and early 50's. Early PV cells were extremely expensive to manufacture and build, and efficiency of the cells was not very good. Today, efficiencies approach 20% (sunlight energy in watts/square meter to electrical power in watts/square meter) at the cell level and close to 16% for some panels. While this seems like poor efficiency, it represents tremendous progress in engineering and design. PV panels used to cost upwards of $1000 per watt in the early days of the space program. Now $2.50 per watt and better for bulk purchases is routine. We have come a long way.So what do we use Photovoltaic panels and arrays for? Anything that requires a source of electrons; anything that you can plug into a wall, a car, or power with batteries or a AC converter can be powered by PV panels and arrays. Anything!Do you have a remote well, need lighting in the middle of nowhere? Do you live off the beaten path? Do you need power for appliances, computers, signs, electric vehicles, lawn mowers, weed eaters? You name it and we can design and build you a way to power it; cheaply, reliably, and, once the initial cost is invested for free.Call us today for an estimate and to learn about available rebates and tax credits.
