Unless it is covered or disconnected, any number of solar panels would cut down your monthly electricity bill from the utility company. However, solar panels may well increase your effective electricity bill.
Renewables are tricky to calculate; solar panels have a "peak power" rating but you'll probably not achieve this. As well, where you are on the planet will affect how much sunlight you receive.
Rule of thumb: assume you will get 60% of the panels peak rating as a daily average. A 200 W panel would (by this RoT) give you 120 W of power. Assuming 12 hours of effective daylight (average over the whole year, dawn/dusk ) yields 12h * 120W = 1440 Wh. That is 43 kWH per month for a 200 W panel.
The actual number will vary...if you're in Phoenix or Madrid the number is quite a bit higher. If you're in Saskatchewan the number will be lower (particularly as you'll have to sweep snow off the panel in the winter!)
You'd then need to determine how many years you'll annualize your installed system cost over. System cost is not just the panel but also the installation labour, inverters, wiring, batteries, controllers, and (possibly) financing costs.
For rough numbers, let's assume that you installed ten panels with a total system cost of $20k [NOTE: fictional number for demonstration purposes only], and that you're going to annualize your cost over ten years.
So now look at your utility bills over the year: does the average exceed 430 kWH? Probably...so you're not likely to run the meter in reverse. But you would make a dent in the bill you receive every month.
And (here's the kicker): by this calculation your effective electricity bill (utility company plus your monthly "cost" for the solar system) is going to increase: you're probably not paying $0.39/kWH...more like $0.08/kWH in the US (here in Ireland I'm paying EUR 0.17/kWH = US$ 0.27/kWH).
The actual numbers in your case will probably vary. Talk to a solar panel installer and they'll be able to help you do more accurate calculations. BUT VERY IMPORTANT: be sure to get local references of installed customers and then talk to the references. The company wants to sell you panels so their calculations will be optimistic. Only people with similar systems in your area will be able to tell you what they are able to achieve in terms of panel efficiency and productivity.
One final point: in year 11 of the above scenario, your solar panels become "free" to operate. Except that:
The net result is that year 11-20 you'll probably start needing to pay for maintenance and replacement costs...so it isn't likely to be free.
A far more cost-effective option to consider: solar water heating. System cost is lower, and instead of displacing electricity (in the US, mostly coal-based) you'll likely be replacing natural gas. In all liklihood, natural gas prices in the US will increase faster than electricity prices, so solar water heating is a more effective hedge.
The cost of solar energy has decreased significantly due to advancements in technology and increased efficiency. The benefits of solar energy include lower electricity bills, reduced carbon emissions, and energy independence. Additionally, solar energy is a renewable resource that can provide long-term sustainability for the environment.
I consider that the nuclear energy is a chance for the future.
Renewable energy sources are Solar, wind, Geothermal, Tidal are prime energy sources
Solar energy, wind energy, and geothermal energy are all examples of renewable energy resources.
Solar energy is generated by capturing sunlight and converting it into electricity using photovoltaic cells, while wind energy is generated by harnessing the kinetic energy of wind through wind turbines to produce electricity. Solar energy relies on sunlight availability, while wind energy relies on wind speed and consistency. Both types of energy are renewable and clean sources of electricity.
The main forms of solar energy are photovoltaic (PV) solar power, which converts sunlight directly into electricity through solar panels, and solar thermal energy, which captures the sun's heat to generate electricity or provide heat for residential or industrial use. Other emerging forms include concentrated solar power (CSP) and solar water heating systems.
a lot
Some common questions about solar energy include: How does solar energy work? What are the benefits of using solar energy? What types of solar panels are available? How much does it cost to install solar panels?
£100,000.00
well it doesn't cost anything to get solar energy 'cus it comes from the sun
$18000-$40000
like a boss
Solar generators converts solar energy into electrical energy. So it will give you electricity at a very low cost. Its pollution free, cost-effective, and low maintenance.
its a higher cost in money because in order to get solar energy u have to have solar pannels
$158,090,964,630.54
cost a lot
Less then regular electricity.
There are many benefits of solar energy systems, the primary benefit being the savings to the environment when compared to the burning of fossil fuels.
