Benefits Of Solar Panels

Residential Solar Power 101: How home solar power systems work

Now you know what they are and how they work, we can tell you why to care.

  • Renewable energy source: Solar energy is accessible for as long as we have the sun, which scientists reckon will be at least five billion years. Its truly a renewable energy source, doesnt produce gases, pollute water or create noise. Its a green dream.
  • Reduces electricity bills: Since youll be generating some of your energy needs from solar panels, your total electricity bills will drop. You can also make money by selling any unused electricity back to the grid. And you can still switch gas and electricity suppliers when you have solar panels.
  • Timing: Household energy usage needs tend to be higher in the afternoon and evenings, when people are at home. This is perfect as solar energy reaches maximum production around those times. Note: solar panels dont work at night.
  • Low maintenance: Solar panels dont require much maintenance just cleaning a few times a year. Warranties are usually for 20-25 years and the inverter only needs to be changed after 10 years.

Best For Small And Portable Off

For people looking for portable solar power for when theyre camping or using RVs, there are many options, including Home Depot, Amazon, Best Buy etc. Brands that have good reputations are Grape Solar and Renogy both are American companies.

However, there are now many brands in the market, many with much lower prices just make sure to check reviews and warranty details before making a purchase.

How Much Does An Off

The prices of off grid systems range from about $50 to tens of thousands of dollars. Thats because off grid solar has such a huge variety of applications.

If we talk specifically about off-grid solar kits that can power an entire home, then prices range from $12,000 to $50,000.

You can get an idea of pricing from the table below it shows popular off-grid kits for different end-use requirements:

Benefits Of A Solar Power System

One of the biggest and apparent advantages of a solar power system is that it is pollution-free. With our planet constantly battling the environmental crisis and our excessive dependence on the use of fossil fuels, using a renewable energy source to generate electricity is a significant step in the right direction.

A solar power system is not only environmentally friendly but is also extremely easy to maintain. There is virtually no maintenance that goes into a solar power systems smooth and hassle-free functioning for up to 30 years. It is a one-time investment with long-term returns.

Moreover, a solar power system is efficient. There is no room for wasting any energy because the electricity that is produced and not used up by your home appliances is always either stored using batteries for later use or transferred to the grid in exchange for credit, as mentioned above.

Additionally, the use of a solar power system does not warrant the need to switch it on whenever you want to use it and off otherwise. The system is designed to perform this task automatically. It also determines when to use electricity from the grid or send electricity back to the grid automatically. The amount of energy being produced, used, stored, or moved around, can be checked from the inverter, which displays the numbers 24/7.

What Is Solar Power For The Home

A glimpse into how solar panels work

Homeowners who install photovoltaic power systems receive numerous benefits: lower electric bills, lower carbon footprints, and potentially higher home values. But these benefits typically come with significant installation and maintenance costs, and the magnitude of the gains can vary widely from one house to another. This article will help homeowners make the financial calculations required to determine the viability of solar power in their homes.

Solar Inverter Converts Power Into Usable Ac Electricity

Home appliances are designed to use alternating current electricity, so the DC power generated by the solar cells needs to be converted before its supplied to the home. This function is performed by a solar inverter.

In most homes, there is a single string inverter installed. These string inverters, also referred to as central inverters, receive the combined power from all solar panels before converting it.

However, solar inverters can also be installed at the module level in those cases, small microinverters are attached to each individual solar panel to perform the AC-to-DC conversion.

Although it often gets overshadowed by solar panels, the solar inverter plays a crucial role in solar power production.

How Much Solar Power Does The Uk Currently Generate

Somewhat surprisingly, the UK is the seventh largest producer of solar power worldwide after China, the USA, Japan, Germany, India and Italy. We generate more solar power than sunny Spain.

The current peak solar electricity generation record seen by our Electricity National Control Centre is 9680MW on 20 April 2020 enough to boil five million kettles!

Grid Connected Vs Off

There are some differences to account for if youre looking to roll out a solar battery backup system off-the-grid, as compared to being connected to the grid.

Well-designed off-grid systems should be able to store enough electricity for two to three days without much sun, during the coldest times of the year.

As such, youll need a much larger battery capacity, and more solar panels to charge them up. This makes off-grid battery backup systems much more expensive than grid-connected solar systems.

Unless youre in a very remote area and having the ability to use stored energy is worth it to you, the added cost of battery backup can be prohibitive.

What About Alternative Solar Technologies To Photovoltaics

Home solar panels system | How it works

Weve been talking about , or PV, in this article, because its the most common type of solar energy generation, especially for homes and businesses. But theres more out there, and they work in different ways than traditional photovoltaic solar panels. Two of the most common alternative solar options that work differently than PV panels are solar hot water and concentrated solar power.

A Bit About Inverters

Inverters play an important role in how the battery stores and converts solar energy. While solar panels generate electricity in direct current, or DC, the electric grid and homes generally use alternating current, or AC. An inverter can convert AC to DC or vice versa, and most solar batteries include an inverter to store the energy in DC form, as well as an inverter to convert it back into AC to be used in the grid or the home.

Because inversion of current is not perfectly efficient, battery producers are always experimenting with how to invert less often and increase the efficiency of the battery. As a result, some batteries will not have inverters for both input and output included in the system. Talk to your solar installer about the battery system you’re considering so that you can make sure you have all the external inverters you need.

How To Install Grid

Your best bet is to go with a residential solar installation company. A solar system must be custom-designed to fit the needs and available sunlight at your home. A professional installer will know things most homeowners may not have thought of. Are you are in an area with ToU billing? Or which way should your panels be facing to get a better return on investment? Customers on high evening ToU rates should face their panels south/southwest. By facing the system south/southwest, the homeowner gets paid at peak electrical rates instead of paying peak electric rates.

How Does The Solar System Work

The solar system, our home in space. We live in a peaceful part of the Milky Way. Our home is the solar system, a four and a half billion year old formation that races around the galactic centre at 2,000 kilometres per hour and circles it once every 250 million years.

Our star, the sun is in the center of the solar system. Its orbited by eight planets, trillions of asteroids and comets, and a few dwarf planets. The eight planets divide into four planets like ours- Mercury, Venus, Earth and Mars. And four gas giants Jupiter, Saturn, Uranus and Neptune.

Mercy is the smallest and lightest of all the plants. A Mercury here is short of a Mercury day which leads to fluctuations in temperature. Mercury does not have an atmosphere or a moon. Venus is one of the brightest objects in the solar system and by far the hottest planet. With atmospheric pressure that is 92 times higher than on earth. An out of control greenhouse effect means that Venus never cools below 437 degrees Celsius. Venus also doesnt have a moon.

Earth is our home and the only planet with temperatures that are moderate enough for a surface of liquid water. Furthermore its so far the only place where life is known to exist. The Earth has one moon. Mars is the second smallest planet in the solar system and hardly massive enough to keep a very thin atmosphere. Its Olympus Mons is the largest mountain in the solar system, more than three times as high as Mount Everest. Mars has two small moons.

Solar Basics Pt 3 : How Do Home Solar Systems Actually Work?
  • Solar Panels

    Solar panels are made of photovoltaic cells that convert sunlight to direct current electricity . As long as rays are hitting your roof, rain or shine, your panels are converting solar radiation into DC electricity. But in order to get the kind of power needed to turn the lights on in your living room, youll need an inverter.

  • Inverter

    The inverter is a device that takes the DC electricity produced by your solar panels and turns it into alternating current electricity . Its typically installed on an exterior wall of your house, or in the garage.

  • Main Electric Service Panel

    Solar electricity from your inverter flows to the electrical panel, and then into to your home where it powers your lights and appliances. Or, if you generate more solar energy than you use, it flows into the utility grid and while you rake in the solar credits.

  • Sunrun Meter

    Your Sunrun meter monitors your system production and sends the information to Sunrun through a wireless signal. Since it tracks your energy production 24/7, it will automatically alert Sunrun if it detects problems or irregularities.

  • Net Meter

    Speaking of solar credits, the net meter measures the amount of electricity you draw from the grid, and how much excess solar electricity you push into it. So when you use less electricity than you make, you get credit from the utility company. Sounds pretty sweet, right?

    Solar Panels For A 1500 Square Foot House

    The average home in the United States is roughly 1500 square feet. With a home of this size, the typical electric bill comes in around $100 month. In order to cover the electricity for this home, you would need an estimated 15-18 solar panels.

    For example, a typical fridge may be rated for 250 watts and runs for 4 hours a day. 250 watts X 4 = 1000W. A 1k watt is equal to 1 kWh of energy in a day.

    This, of course, is a general estimate and eclectic usage, sunlight hours, location, and the type of panels can change this amount.

    How Does Solar Power Work

    So how exactly does solar energy work?

    It goes through four primary steps.

    1. Solar panels capture sunlight

    The solar panels that we install onto your rooftop are designed to capture a percentage of the sunlight that hits that part of your roof. We determine where the solar panels should go based on the direction your house is facing, the size and shape of your roof, and your homes energy needs. This helps your solar panels capture as much sunlight as possible to maximize the amount of clean solar energy you have to help you power your home.

    2. Your solar energy system converts the sunlight into electricity

    Once the solar panels have captured the sunlight, the inverters on your solar energy system convert that sunlight into electricity that you can use to power your home. More specifically, it takes the DC electricity and converts it into AC energy which is actually used to power our houses and appliances.

    3. You then use that energy to power your home

    After the sunlight has been converted into usable electricity, the process is fairly straightforward. Your lights can turn on and off. Your appliances are able to run. And you can even use that electricity to charge an electric car if you have one.

    4. Any remaining energy either goes to the grid or gets stored for later use

    Depending on where you live, you can get credits from your local energy company for your excess electricity, but storing it may be more useful. It just depends on your specific situation.
