El Dorado Hills, CA

Solar Panels – We Help Homeowners Live Powerfully!

El Dorado Hills is perfect for Solar Panels!

The demand for solar supplies and available suppliers in El Dorado Hills has developed over the last decade. To make the city more accessible, prices have decreased as a result. At the same time, financing and purchasing options have improved for California homeowners, making solar less of an anomaly and more of a normal. The more you know about your solar options, how solar works, and what questions you might ask, the more likely you are to make the right solar buying decisions.

How Solar Systems Work

The bulk of home solar systems are electric solar systems (or photovoltaic, sometimes referred to as PV). These devices can produce electricity through a few primary hardware elements: a panel that converts light from the sun into electricity and an inverter (or several inverters) that turns the sun’s current into an alternating current that can be used by your home.

Thinking about adding Solar to your Home?

There are various forms of “going solar” and you need to be sure which one is right for you. One of the principal traps people get into is not getting “enough solar”. Consider how much solar you need before making this decision. Many companies are attempting to market smaller devices to promote the actual use of energy than you need. If you want to cover just half of your energy, which is also perfectly good, just know what you want and what you get.

Do Solar Panels Still Work When it’s Cloudy or Raining?

Solar panels, while most efficient in direct sunlight, may use direct or indirect sunlight to generate electricity. Even when the sun is reflected or partly obscured by clouds, solar panels can still work. The rain helps keep panels running effectively by washing away any dust or dirt. Excess energy generated by your panels during sunny hours can offset the energy you use at night and other periods when your system is not running at full capacity.

How Solar Impacts your Property Value

Studies have shown that homes with solar panels sell for more than homes without them. However, your property value will only increase if you choose to buy your solar panel system, rather than lease it. In some parts of the nation, going solar would increase your property value more than a kitchen renovation.

Did You Know There Are Solar System Warranties?

Typically, solar power systems are a fairly smooth and solid investment, they require limited maintenance and are built to last however, all systems should come with a warranty included in the bid but some companies may not include them without you asking. All warranties are not equal, and you should always ask what the warranty length is and on what equipment.

There are typically two types of warranties; one is an equipment warranty on panels and inverters which ranges from 20-20 years on the panels, 5 to 10 for the inverts, and the other is related to the quality of the installer’s work.  i.e. a guarantee that they didn’t make holes in your roof that will lead to leaks. This is normally an average of 10 years.

Frequently Asked Questions


How heavy are solar panels? This is a common question! On average, solar panels and the mounting equipment weigh 2-4 lbs per square foot (10-20 kg per square meter), which is usually within the acceptable limits of your roof.


Photovoltaics (PV) are best known as a method for generating electric power by using solar cells to convert energy from the sun into electricity. The photovoltaic effect refers to photons of light knocking electrons into a higher state of energy to create electricity.


Solar energy is, simply, the energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. Electricity can be produced directly from photovoltaic, PV, cells.


When certain semiconducting materials, such as certain kinds of silicon, are exposed to sunlight, they release small amounts of electricity. This process is known as the photoelectric effect. The photoelectric effect refers to the emission, or ejection, of electrons from the surface of a metal in response to light. It is the basic physical process in which a solar electric or photovoltaic (PV) cell converts sunlight to electricity.
Sunlight is made up of photons, or particles of solar energy. Photons contain various amounts of energy, corresponding to the different wavelengths of the solar spectrum. When photons strike a PV cell, they may be reflected or absorbed, or they may pass right through. Only the absorbed photons generate electricity. When this happens, the energy of the photon is transferred to an electron in an atom of the PV cell (which is actually a semiconductor).
With its newfound energy, the electron escapes from its normal position in an atom of the semiconductor material and becomes part of the current in an electrical circuit. By leaving its position, the electron causes a hole to form. Special electrical properties of the PV cell—a built-in electric field—provide the voltage needed to drive the current through an external load (such as a light bulb).


A photovoltaic (PV) system needs unobstructed access to the sun’s rays for most or all of the day. Shading on the system can significantly reduce energy output. Climate is not really a concern, because PV systems are relatively unaffected by severe weather. In fact, some PV modules actually work better in colder weather. Most PV modules are angled to catch the sun’s rays, so any snow that collects on them usually melts quickly. There is enough sunlight to make solar energy systems useful and effective nearly everywhere in California.


The size of solar system you need depends on several factors such as how much electricity or hot water or space heat you use, how, the size of your roof, and how much you’re willing to invest. Also, do you want the system to supply your complete energy usage or to supplant a portion of your higher cost energy usage? You can contact a system designer/installer to determine what type of system would suit your needs.
