How Reliable Is Solar Power

Solar Power System Reduces Concern Of Increasing Power Prices

SKF Reliable solar power system solutions

Most homeowners understand that electricity is getting more and more expensive. In fact, the cost of electricity has grown significantly in the past decade, with an average increase of around $0.20 per year. This cost will keep going up, which means electrical costs will grow, too. With the installation of solar panels, it is possible to be protected from these growing costs. That is because the home or business will be producing energy and can avoid having to purchase it from the utility company.

How Do Solar Panels Work

Solar panels are affixed to the roof of a building where they intercept the rays of the sun and turn them into usable, renewable energy to power the home or office.

When you have solar panels installed, you are connected to the power grid. The panels receive sunlight and use it to produce direct current energy. This energy is then fed into a solar inverter where it becomes AC energy which can be used to power the appliances in your home.

During the day, your home will use the solar energy it generates. If you have an excess of solar energy, it will be fed to the power grid where your electric company will give you credits for the extra energy. At night or on cloudy days, you can draw on these credits to offset the cost of using the power grids electricity.

How Reliable Is Solar Power

With solar power being flaunted as one of the realistic alternatives to the burning of fossil fuels, it is only natural that enlightened thoughts are turning to the reliability of the energy it can create.

After all, the sun is an intermittent energy source. It does not always shine, with most countries experiencing cloud cover for large portions of the year.

There is also the issue that the sun is only available for, at most, 12 hours out of every 24. Could the worlds energy demands really be sustained from what seems like such an unreliable heat source?

The answer is probably no, which is why solar energy is only being spoken of as one of the options for continued energy production.

However, solar energy is one of the most viable of the options mentioned, even if it could not meet the entire worlds demands for energy by itself.

The reason for this is simple the sun is a constant. The sun will continue to shine for as long as there is life on earth by the time the sun begins to dim, the earth as we know it will begin to die.

Unlike the expendable resources of coal and oil, this makes the sun very dependable it will be here for as long as the world will.

The sun is also relatively easy to tap into, as it shines directly onto earth and needs no human interaction for it to work to its full potential.

This is certainly more viable than having to dig into the earth for coal, or send rigs out to sea to collect oil.

Experts Agree: We Can Significantly Ramp Up Renewable Energy Without Affecting The Reliability Of Our Electricity Supplies

The authorities responsible for operating the nations power grid regional transmission organizations and independent system operators have all published or participated in studies evaluating how increased renewable energy supplies would affect the electricity system. These studies have overwhelmingly shown that higher levels of renewable energy can be achieved regionally without affecting the reliability of electricity supplies. They also highlight that ramping up renewables can result in significant cuts in global warming pollution.

Will You Always Have Electricity If I Go Solar

When it comes down to it, as long as your system is tied to the electric grid, you will always have access to as much electricity as you need, given the grid is up and running.

While its true that solar panels can only produce electricity when the sun is shining, you still have full access to the electric grid. And with net metering or New Yorks Value Stack, youll be fully compensated for any electricity your system produces that you dont use through a credit on your electricity bill. This means that your solar system can produce extra free electricity while the sun is shining to use at night or in poor weather.

However, a common misconception is that with solar, youll have electricity even when the grid goes down or the lights go out. Because your system is tied to the grid, it is required to shut off and stop producing until the grid is back up and running, unless you invest in a battery or other energy storage system.

Definition Of Reliability In Relation To Electricity

From arena.gov.au:

Security and reliability are terms used to discuss the strength and stability of the electricity grid, also known as an electric power system.

The security of an electricity grid is its technical resilience , namely its ability to quickly respond and remain stable when unexpected events occur.

Examples of such events include generators breaking down or transmission lines failing.

Reliability is the ability of an electric power system to deliver electricity in the quantity and quality demanded by energy users.

Both are said to have reliable and secure electricity grids according to some reports.

Germany

Germanys annual power supply interruption has decreased from 2006 to 2017:

When systematic monitoring started in 2006, average outage times exceeded 20 minutes. In the same period, the share of renewable electricity production in Germany rose from 11.3 to 33.1 percent, mostly from fluctuating sources such as wind and solar power stations

Will Solar Power Be A Reliable Source Of Energy For My Home

Since solar panels depend on the sun they wont be much good at night and will produce less energy depending on the season. Luckily, there two easy ways to overcome this obstacle:

  • Net metering: A law known as net metering requiring utilities to compensate those who export excess solar power to the grid. In most cases you will be credited at the same rate you purchase power at on a cents per kilowatt-hour basis.
  • Batteries: Your solar panels will charge your batteries throughout the day and at night the batteries will power your home.

In most cases homeowners elect not to install batteries with their solar system. This is because net metering allows you to harness the economic value of your solar energy without the large financial investment in batteries.

Its hard to overstate just what an amazing incentive net metering is. It gives you the benefit of 24/7 grid connectivity while allowing you to sell surplus solar production during the day, cancelling most or even all of your power bill.

Tests Performed By Pvel And The Failures They Expose

The PVEL tests are smaller in number but more severe than the UL and IEC tests. For example, the PVEL thermal cycling test involves 600 cycles in an environmental chamber that cycles between hot and cold temperature which is 3 times as many cycles as the IEC test.

Heres a list of the tests performed:

  • Thermal cycling: Solar panels are baked at +85°C, then frozen down to -40°C in an environmental chamber for 600 cycles, or about 84 days.
  • Damp heat: The panels sit in a chamber at a scorching 85°C with 85% humidity for 2,000 hours, simulating the effect of operating in damp conditions for many years.
  • Mechanical loading: For this punishing test, the panels are loaded with 1,000 Pa of force 1,000 times, then cycled between -40°C and 85°C 50 times, subjected to the damp test for 20 hours, before finally being frozen to -40°C.
  • Potential-induced degradation: Solar panels can experience a type of degradation called PID that happens when theres a large voltage difference between the solar cells and the metal frame of the panel. This PID test applies up to -1,500 volts to the panel under damp heat for 192 hours.
  • Low light testing: The output of a solar panel drops when theres less light, of course, but the drop isnt linear: solar cells are less efficient in low light. They also lose efficiency when hot. Both low light and high temperatures are tested to show which panels perform best in these conditions.

Solar Panels Could Damage Your Roof

We all want to consume less electricity when were not using it. We can use solar panels to help generate electricity, but they might be damaging your roof in the process.

Improper installation of solar panels could leave holes in the roof that would lead to water leakage causing significant damage to both the exterior and interior of your home. To avoid this, ensure to conduct proper research on installation companies and ensure they have good reviews.

Solar panels need additional support to be securely mounted, due to the weight of the panels. If the roof is not durable or has any weak spots, the panels could cause your roof to crack or flatten over time due to additional weight. We recommend a proper assessment is done on the integrity of your roof, to confirm the roof can withstand the weight of the panels.

If the panels are installed at a steep angle, it can cause them to falter over time causing damage to the roof. If the panels are too high or low on the roof issues may arise in the Attic or interfere with gutters functioning properly.

These potential issues may void any current Roof Warranty. It is important to check with your roof installation company to ensure the addition of any solar panels would not interrupt coverage.

Weighing Investments In Solar Energy

Distributed energy production combined with storage or special grid design can provide increased energy security during grid outages due to extreme weather or security problems. PV solar also has low water requirements, making it useful for regions with a limited or unreliable supply. Land use requirements for solar energy can be further minimized with distributed rooftop solar and other multi-use sites including shade structures . Quality solar panels also can pay back the amount of energy required for their production decades before retirement, and greatly reduce emissions in addition to financial savings. Compared to energy generation from traditional fuels, solar energy reduces pollutants that currently impact human health from infancy through adulthood, including cardiovascular and lung risks. Ratings for sustainability of manufacturing processes are also available, such as the Sustainability Leadership Objectives. Financially, region-specific incentives, as described in the DSIRE database, make investing in solar energy more affordable. Today, solar panels are often used to reduce energy expenses, provide grid back-up power, and power homes, vehicles, and commercial buildings. Solar energy systems have improved in efficiency, reliability, and price. Continuing to utilize and develop best practices and certifications drawn from more than a half century of PV experience and experiments can increase the return on investment and reduce risk for stakeholders.

Electric Vehicle Charging Stations Are Becoming More Common But Are They More Reliable

Solar Power: The Good, the Bad and All the Facts You ...

Municipalities in Nova Scotia large and small are starting to install electric vehicle charging stations. At least one driver is hoping they will be well maintained.

The town of Mahone Bay will have eight units by the end of December.

According to the mayor, it makes sense to encourage people to consider electric vehicles because Mahone Bay has its own utility and 84 per cent of the power comes from wind and solar.

“I think the municipalities are the ones that can provide leadership,” said David Devenne, “Especially the ones that have their own utilities, we can have an impact on both ends.”

Halifax has just adopted an electric vehicle strategy. It includes plans to install 1,000 charging stations over the next 10 years. There are currently more than 100 of them across the province.

An electric vehicle driver from Halifax hopes the new charging units will have ongoing maintenance.

Shannon Bradley bought an electric vehicle in April 2020. Five months later, she tried to attend a family function in the Parrsboro area.

Bradley planned to charge the vehicle in Masstown but the charging station did not work. She backtracked to Truro, then to Stewiacke, to try to use units, but they didn’t work either.

“So we took our bawling, crying kids back home,” she said.

Bradley said she has seen comments from other electric vehicle drivers who have had problems with a variety of the charging stations.

According to Leithan Slade, a spokesman for Petro Canada, its network is reliable.
