What is solar energy?

Solar energy takes advantage of the sun's rays to generate heat or electricity. It is an infinitely renewable energy resource and unique for its ability to generate energy in a quiet, clean, and consistent manner. Can't beat the sun for being oh-so-cool!

How do solar photovoltaic cells work?

In layperson terms, photovoltaic cells are comprised of a semiconductor material such as silicon. Added to the silicon are the elements phosphorous and boron which create conductivity within the cell and activate the movement of electrons. The electrons move across the cell when activated by the sunlight's energy into the electrical circuit hooked up to the solar panel.

How much does a solar electric power system cost?

A 100kW solar power system will cost approximately Rs.60,00,000. That total includes the cost for all components - solar panels, panel mounts, and inverter - and labour associated with installation. It does not however, reflect all the avoided costs, such as the tax breaks and the credits received through net metering.

How much will I really save on my utility bills from a home electric solar power system?

大发体育Of course this is a relative question. It depends, in part, on how much electricity you use and how efficient the appliances are that you operate. That said expect to generate excess electricity in the summer (when days are long) which can potentially offset the energy you use from the grid in the winter. A combination of energy efficient appliances and solar power can help reduce your energy bill substantially.

How much maintenance do solar energy panels require?
Solar photovoltaic panels require little maintenance - periodic wash with clean water to remove dust and debris.
When should I seek a solar professional?

Although solar energy systems work in parallel with conventional residential, there are quirks in the process well suited to seeking out professionals who specialize in solar power installation. Solar installation professionals can help you determine the type and size of system most suited for your needs.

What should I ask a solar professional installer?

Professional solar installers can take the guess work out of installing a solar power system。 Whether you are considering solar photovoltaic for industry, residence or institution, a solar pro can help you determine the type and size of system that will work best and guide you through the process。

How can I calculate the cost and payback time from a solar power installation?

You can estimate how much a solar electric system may cost if you determine your current energy needs and costs and compare against your future anticipated use. Once you have a sense of how much energy you use, you can evaluate the cost of purchasing and installing solar power technology.

How long will it take to install a solar power system?

大发体育Depending on the capacity of the system, planning, configuring, and doing any custom ordering for your solar energy system can take up to a few weeks. However, the installation process itself can typically be completed in only a few days time, in many cases even less.

What components do I need to install a grid-tied solar electric system?

You will need a photovoltaic array to capture the sun's energy, a solar inverter to convert the direct current (DC) produced from the photovoltaic cells into alternating current (AC) used by your home, and a utility meter - called a net meter - that can record both the electricity produced from your internal power system as well as any power you may use off the grid. These three system components are then connected through a series of wiring. The photovoltaic panels are secured to your roof with panel mounts.

What is a net meter?

Net meters look very much like other outdoor meters with one notable exception - they spin both forwards and backwards recording both the power produced and power used.

Do I need battery backup for my solar panels?

Probably not - a backup battery bank can add as much as 25% in cost to a residential solar PV system. It's not necessarily more efficient either - a same sized solar array will yield about 7-10% less energy if it's battery-tied than its grid-tied counterpart.

Though you will remain tethered to your local utilities' grid, you will not have to worry about not generating enough power. You also gain the advantage of offsetting rising utility costs. Most solar photovoltaic experts do not recommend adding a backup battery system unless there is concern about a long utility outage or the site is in a remote location.

How much space do I need for a solar photovoltaic system?

In bright sunlight, a square foot of a conventional photovoltaic panel will yield 10 watts of power。 That's a helpful rule of thumb for calculating a rough estimate of how much area you might need。 For example, a 1000 watt system may need 100 square feet of area, depending on the type of PV module used。

How many solar panels do I need for an electric solar power system?

The size of the photovoltaic system is correlated to your energy-use needs, available space for a system, and overall costs for the system components and installation. Please contact us for us to help you determine the best size for your solar photovoltaic system.

How much shading is too much for solar photovoltaic panels?

Unfortunately shading a photovoltaic system dramatically decreases its output。 Just shading the bottom row of wafers alone amounts to an 80% reduction in efficiency。 So above all, don't shade your array!

How do I know if solar panels will work at my site?

Take a look at the position of your site - and particularly your roof. Ask the following questions:

  • Is there good southern exposure? Orienting solar panels to the south maximizes the effectiveness of energy collection.
  • Is the exposure free of trees or buildings that could shade the panels or drop debris on them? Shading photovoltaic panels dramatically reduces their effectiveness.
  • What is the pitch of your roof? Most roofs, from flat to 60-degrees can accommodate photovoltaic panels.
Do I need to have south facing exposure to have a solar energy system?

Although southern exposure increases the effectiveness of a residential solar power system, your site may still work for solar power without having south facing exposure。 Seek advice from a professional solar designer or installer to ensure success。

What other factors are important to consider when installing a solar energy system?

The location and the local climate will play into where you place and how you install your solar electric system. Wind speeds and salty air can all affect a solar array. Understanding how those inputs effect performance will determine the types of mounts or how the arrays are angled. A solar pro is likely quite knowledgeable and can help you design that works well for you.

Will I have power in a blackout?

To ensure your safety, the inverters on the panels shut down automatically during a blackout. When power is restored to the grid, your system automatically resumes operation.

How do I know if my location receives enough solar energy to make electricity?

We conduct a complete site examination, including shade analysis, to determine whether solar is a viable solution for your location(s).
