How Much Electricity Does A 2kw Solar Panel Produce

Grants For Solar Panels Ireland

Doubling My Solar Power from 1kw to 2kw! Much Better.

Depending on your circumstances, you may be entitled to a solar panel grant from the Sustainable Energy Authority of Ireland . The grant contributes towards the cost of a solar panel installation in Ireland. To comply, your home must have been built before 2011. It must also have been occupied since then. However, if the SEAI has already provided assistance to this address, the grant wont be accessible.

Are solar panels worth it in Ireland if you are awarded an SEAI grant? It certainly contributes a great deal towards the cost of your solar panels. On average, a grant for solar panels installation might be worth between 1,700 2,500. There are different categories of solar panels that might affect the amount.

PV solar panels with a rating of 2kW might have a grant of 1,800. 3 kW solar panels could have a grant of 2,100. If your installation has 4 kW solar panels, you could receive 2,400 towards the cost. Some systems use a battery for storing excess solar electricity that you can use at any time. There is a grant of 600 to help towards the cost of battery installation. Electrical contractor, JK Services is one of the leading solar panel installation companies in Ireland. We are highly qualified in providing specialised installations of solar panels throughout Cork and the rest of the country. You can appoint us as your solar panels installers when you apply for your grant.

How Many Solar Panels Does A House Needs

To calculate your solar requirement you have to perform the following steps

  • Look into your latest electricity bill and take an average of your last 12 months power consumption. The values should be on the electricity bill. if you cant find it there open the electricity provider website you will find it there.
  • Once done with finding your average monthly consumption, divide that figure with average monthly generation from 1 kW of solar panels .
  • This will give you the kilowatt of solar panels required for your house. Then divide the KW with wattage of individual solar panel you will find the total number of solar panels needed for your house.
  • Lets see an example to get the idea crystal clear.

    You look into your latest electricity bill and find out monthly consumption for the last 12 months is as follows 500,120,300,400.600.550,100,800,600,300,450,400.

    Lets take an average of these 12 values to get average monthly requirement of power.

    Average = Sum of values / No of values.

    In our example sum of values = 5,120

    No of values = 12

    Hence average is 426.66 KWH

    So your house needs on an average 427 KWH of electricity every month.

    Now we know that average monthly generation of power from 1 kW of solar is 120 KWH

    Therefore your solar requirement is 427/120 = 3.55 kW.

    If we assume you are planning to use 330 Wp of solar panel then no of solar panels required to power your house with solar will be 3550/330 = 10.75.

    We can round it of to 11 solar panels each of 330 watts.

    How Much Should I Pay A Contractor To Install The Solar Kit

    Any licensed general, electrical or solar contractor can install our solar kits. If you select to hire a contractor to install your solar kit, you should expect to pay approximately $1.00 per watt for labor, wire, conduit, fittings, breakers and other miscellaneous electrical components to complete the solar system installation. For a 2 kW system, which is 2,000 watts, you can expect to pay $2,000 for installation. If needed, we can assist you with finding a contractor.

    Solar Power Peak Output

    Peak output can also vary depending on what angle your panels are installed.

    A system installed on a flat roof will perform better in summer and worse in winter compared to the average, whereas a system installed on a steeper roof will perform better in winter because the panels will be tilted towards the lower winter sun.

    A system installed on a steep roof or with tilt frames can actually reach a higher peak-output in winter compared to summer.

    Peak output will always be less than the panels rating because a panels rating is based on its performance in flash test in a testing laboratory where conditions are perfect. In the real world, there are a whole number of factors that slightly reduce a panels output such as the angle of the panel in relation to the sun , the time of day, the weather, pollution or haze in the air, the temperature , patchy shade, and dirty panels.

    Furthermore, the output from a panel is reduced by efficiency loss as it is converted from DC to AC by the inverter. Most inverters have an efficiency of around 97% or so, but already that takes output in perfect conditions from 5kW down to 4.85kW.

    How To Calculate Solar Panel Output For Your Home

    Solar Power 101: How Much Power Does a Solar Panel Produce?

    There are three ways to calculate the electricity production you are likely to get at your home from solar panels, how many you need and how many square feet of roof space they will take up. There is the lazy way, the very lazy way and the science nerd way.

    The science nerd way is to look up the meteorological data for your location, measure the direction and tilt of your roof and examine your power usage patterns and net metering scheme available from your utility to work out how much solar you need.

    The easy way is to use one of the free online solar panel calculators that already have all of this information programmed into them so that when you enter your zip code, power bill and utility provider they automatically work out all these things for you as well as estimate the cost of solar, based on solar company pricing in your area.

    The downside of this is that you have to enter your details and they will try and offer you quotes for solar but lets face it, with net metering and a 26% solar tax credit now available it is probably a good thing to get proper quotes for solar anyway.

    Online estimates are not as accurate as a quote where a solar company has viewed your roof online because the direction, tilt of your roof and any shading affecting your roof will affect the energy production you will get from solar panels and this is the only real way to know you have accurate information on which to make a decision about solar.

    How Do I Improve The Output Of My Solar Panels

    There are 4 key factors that will determine just how much electricity you can create with solar panels for your property:

    • The size of the system is the most important factor of all. The typical domestic installation is a 3.5kW system, which is normally around 12 panels. A smaller 1kW domestic system is likely to be only 2 panels.
    • The direction that your roof faces and the angle of the roof comes next. For optimum performance, your panels will need to be on a 35-degree angle, facing south.
    • Having a roof that is not in the shade will increase the amount of electricity you are able to produce. Take a look at the handy table above, which shows you what output volume can be expected from a domestic solar installation.
    • The time of year will also have an impact. During longer daylight hours in the summer you will be able to produce proportionally more power. That said, its important to remember solar panels work from light not heat so will still produce energy all year round.

    How Much Energy Will A 2kw Solar System Generate

    There are a number of factors that will influence how much energy a solar system produces location, orientation & tilt of the panels, the presence or absence of shading and the overall efficiency of the components in the system are chief among them.

    Its convenient to summarise solar system output in a single figure namely, kilowatt-hours per day . But the reality is that most locations receive more sunshine in the summer than in the winter accordingly, PV system energy yields will usually be higher in the summer and lower in the winter.

    The table below provides some rough figures on average daily outputs from 2kW solar systems in a handful of Australias capital cities, as well as the maximum and minimum outputs for summer and winter. All situations assume north-facing aspect, panels tilted at latitude and an overall system efficiency of 85%.

    Theres a much greener future ahead for Ireland. We will need far more electricity, so its yes we believe that solar panels are worth it in Ireland.

    Why You Shouldnt Install A 2kw Solar System In Sydney

    Solar Basics Pt 2: How Much Energy Does One Solar Panel Produce?

    1. The larger the solar system, the larger the government incentive. On a 2kW system, the government rebate is currently around $1,200. On a 3kW system, the government rebate is around $1,950. This extra saving of over $700 helps offset most of the price difference between a 2kW and a 3kW system.

    2. The main European manufacturers of solar power inverters dont make a 2kW model. Both the Fronius Primo range and the SMA Sunny Boy range start at 3kWs. The only 2kW option is to use a Chinese brand or go to the top of the range using Enphase Micro Inverters.

    3. You cant split a 2kW system across different roof sections with a string inverter. You need a minimum of 6 or 7 panels in each direction to create enough voltage to run a solar inverter properly, so for a 2kW array, all panels must be facing the same direction. This may be an issue if you dont have enough roof space to fit all of the panels in a row across one roof section. The way to get around this is to use the latest technology from Enphase, where each panel outputs power independently from the other panels.

    4. If you have a crew of professionals out to your house , you may as well get them to add a few more panels. There are always fixed costs involved in a solar installation, and so the larger the system, the cheaper it is per panel.

    Don’t Miss: How To Get Solar Energy

    How To Tell How Much Electricity Is Being Generated

    When you go to have your solar panels installed, they will come with a meter that is placed in an accessible location within your home. What this meter does is record the amount of electricity that is being produced by the solar system, as well as how much electricity they are exporting back to the National Grid. This then allows you to work out how much you will be paid by the Feed-in Tariff.

    Solar panel manufacturers are also starting to develop online apps for your smartphone that will allow you to access the performance levels of your solar panel. This can be done either via the app, or online from your computer.

    To get the most out of your solar panels and the electricity that is produced by them, you should ensure that you use your appliances during the day as much as possible. This is because it is during the day that the panels will be generating energy.

    You should also try to ensure that your home is as energy efficient as possible. This allows you to get the most out of your free energy. Try to use energy saving lightbulbs, and dont leave electronic devices on standby if you can help it, as these are all contributing factors to excessive energy consumption. Try, also, to only use the washing machine on a full load.

    How Much Energy Does A Solar Panel Produce

    For the sake of example, if you are getting 5 hours of direct sunlight per day in a sunny state like California you can calculate your solar panel output this way: 5 hours x 290 watts = 1,450 watts-hours, or roughly 1.5 kilowatt-hours . Thus, the output for each solar panel in your array would produce around 500-550 kWh of energy per year.

    All solar panels are rated by the amount of DC power they produce under standard test conditions. Solar panel output is expressed in units of watts and represents the panels theoretical power production under ideal sunlight and temperature conditions. Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally considered preferable to lower power ratings. Pricing in solar is typically measured in dollars per watt , and your total solar panel wattage plays a significant part in the overall cost of your solar system.

    On average in the UK we have around 48% of overcast days per year but solar panels still work on cloudy days. Of course, in the winter the sun rises later and sets earlier, so the mornings are dark and the nights drawn in. With shorter daylight hours it does mean generation levels are lower solar panels will produce less energy compared to what they would during the summer months, where daylight hours are longer. Output on a day with light cloud cover can be reduced by as much as half, even down to as little as 10% on a really overcast day. But the energy generated will still be enough to meet the average consumers requirements.

    Your Current Energy Consumption

    Many solar customers desire a system that generates equal to or close to the amount of energy theyre consuming each month. To get a feel for your current energy consumption, look at your watt usage over the last 12 months. Depending on your situation, you may need more or less solar panels to potentially reduce your bill.

    How Many Solar Panels Do I Need To Power A Refrigerator

    How many solar panels do I need to operate a refrigerator? The average refrigerator needs about three or four average solar panels to operate. The average refrigerator found in the United States uses about 57 kWh per month while the average refrigerator uses 58 kWh. Adding these units brings a combined total of 115 kWh.

    How Much Can I Save

    How many Solar Panels do I need to power my house? How much power/energy does a Solar Panel Produce?

    The amount of money you save from your solar system depends on when electricity you use in your home. A 2kW system generates about half the electricity used in an average home and can save you as much as $145 per electricity bill cycle. However, savings of $90 per billing cycle are more likely.

    Again, how much you save depends on the quality of your system. Higher quality systems generate more power over the long term, producing great results well after your systems paid for. So it makes sense to invest in the highest quality system you can afford.
