Useful Information About Solar Panels

Solar power is a fairly recent addition to many homes. There are many questions out there about how they work. Here are a few answers to some of the topics that might be on anyone’s mind who want to know more about this possible global saviour.

 

Solar Panels Absorb Heat Even on Cloudy Days

One of the most frequently asked questions is whether solar panels are able to absorb heat without the presence of sunlight. It goes without saying that solar power would not be much good is they did not work on cloudy days. The panels are designed to absorb heat from as many light sources and on as many wavelengths as possible.

The more light there is, the more heat will be absorbed by the solar panel. If there it is a cold day, however, your water tank may need a covering of some kind to help it retain the heat that it generates.

 

Solar Panels Can Withstand Hail Storms

The manufacturers of solar panels test for resistance against heavy hail and strong winds. They will have certification for evidence of this either in their advertising or on request.

Hail stones the size and weight of golf balls are the standard testing size. Both direct impact and ricocheting hail damage resistance are checked and the panels will have passed this rigorous process.

Cracked solar panels are uncommon in countries like New Zealand, which doesn’t have such weather extremes as the US. The panels are protected from direct hits by being positioned at a slant on the roof. If a small fracture does occur, it will not impact the panel’s performance.

On the odd occasion there may be no visible damage from the hail stone, there may still be a tiny loss of performance. This amount is so negligible that the slight loss will not even be noticed.

 

Converting a 1,500 Square Foot House to Run Off Solar Power Completely

When making the move to completely converting your home to solar power, it is important to first gauge what your electricity consumption currently looks like. A good idea is to install a sensor gauge in the power distribution panel.

Once you have done this, you will have a better idea of where your electricity is being used the most and where it is being wasted the most.

Some of the biggest household wastes of energy can be warm air escaping through cracks in the doors and windows, CFL and incandescent lighting, and poor insulating.

When the need for high amounts of electricity and where energy is being wasted has been sorted out, it is then possible for you to create a plan for the best integrated solar and energy storage.

An initial installation of 21 solar panels with the capacity to generate 320-watts should be enough for the average size home. This will produce 9,000 kWh annually. If this is insufficient, it is always possible to add more battery/storage.

 

Making the move to solar powering your home as never been as important. It will save you money, raise the value of your property, and set an example for friends and family about how valuable a commodity is energy.

£400 Million Solar Energy Farm in Kent has Green Campaigners Up in Arms

£400 Million Solar Energy Farm in Kent has Green Campaigners Up in Arms

 

A £400 million plan to build a huge solar energy farm on top of wildlife marshlands near Graveney, Kent in England, has green campaigners in uproar. The proposed solar farm would stretch out over 890 acres and impact on the rare birds and other small creatures that breed there.

This is bad news for the flora and fauna in the region but good news for the National Grid electricity supply.

 

Why Solar Energy is Profitable

The batteries used to generate solar energy and store it are crucial to any solar energy scheme’s profitability. During periods of sunshine, power is generated during daylight hours when demand is not high.

This then allows the operators of the farm to sell the stored energy to the National Grid at high-demand times. Evening and night time allows the farms to sell the stored energy when they are not in operation.

The batteries to store and capture solar energy can be placed anywhere: industrial areas, farms and even landfills. So why does it have to be plonked on top of this extremely fragile ecosystem that is home to rare birds of prey, skylarks and wading birds?

 

Where Other Countries Place Their Solar Energy Farms

The world’s biggest battery would be housed in the proposed Kent development. This is because the area that will be covered by the farm is planned to be three times larger than the current biggest solar farm, found in Australia.

The huge solar farm built in South Australia by Tesla tycoon, Elon Musk, has a 129 Megawatt hour capacity. The battery planned for the Graveney wildlife marsh in Kent will have storage capabilities of 350 MWhr – all crammed into the edge of the bird’s nesting grounds.

 

Power to over 110,00 Homes

The proposed project is so vast that it will not be ruled by the usual democratic planning procedures. It will be the decision of Business & Energy Secretary Greg Clark as to whether the destruction of the marshland happens or not. It will fall under the Nationally Significant Infrastructure Project approval bill.

The developers of the project, Wirsol and Hive Energy, claim that the farm’s maximum output will provide power to over 110,00 homes in Britain. That is an impressive seven times the output of any current British solar farm.

The catch is that the developers admit the farm will produce power only approximately 11% of the time. Compared to the nearby Medway gas power station that churns out 735MW continuously, the biggest solar farm’s stats suddenly look a little weak.

 

Elon Musk’s Green Policies

Elon Musk built the current biggest solar farm in south Australia and his name has been linked to the potential building of the one in Kent. What is baffling many environmentalists is the conundrum: a billionaire who strives to create a world where the cars are not reliant on fossil fuels on one hand and on the other, a man who is prepared to wipe out an entire ecosystem to build a solar farm on land that could just as easily be a landfill.

 

The solution to this standoff is to think long term. Many areas are viable candidates on which to build a solar farm but to the wildlife who have existed in the Graveney marshlands for hundreds of thousands of years, other choices are not at all possible.

How you might be able to get rid of your utility company

Paying bills to a utility company is a drag, isn’t it? They hike the prices up and aren’t interested in the small people who have to pay the bills.

Take Duke Energy, for example. It’s one of the largest utility companies in America, and serves approximately 7.3 million electricity customers. We’d be talking about billions of dollars in bills, here.

Wouldn’t it be fantastic if you didn’t have to have a provider? No swapping around for the best deals, no annoying sales pitches, and best of all, cheaper prices. Cheaper prices!

It’s a possibility.

 

Brooklyn – A new project.

A new project in Brooklyn has seen residents being fitted with solar panels, which allows them to collect and trade unused energy. Need energy? Buy it off your neighbor!

This isn’t a joke – it’s already been implemented in Germany, where it’s reported that there are over 8,000 producer-customers. Imagine that! 8,000 people producing their own energy, where they can then sell it on a micro-market to their neighbors. WITHOUT a utility company. It’s easy to imagine that the utility companies aren’t very happy about it. Without a doubt, it is stepping on their toes.

Other countries are set to try it, and The Brooklyn Micro-Grid are hopeful that it can be rolled out and emulated in other countries. In 2016, reports circulated regarding India’s electricity crisis, where more than 300 million people didn’t have access to electricity. Imagine if this project was rolled out to countries that have similar issues, where poverty is rife even in the dawn of 2017.

In Bangladesh, it’s estimated that around 35 million people don’t have access to a central grid. This means that the rural households can sell their unused electricity into a network, where the neighbors can purchase it through their phones.

 

Their aim – To create peer-to-peer trading on Blockchain.

(Blockchain is the distributed ledger technologies behind the controversial Bitcoin. While Bitcoin is noted for its ties with the block market, it could be part of a globally groundbreaking project). The idea is to create this independence and bypass the utility companies. It is also Brooklyn Micro-Grids promise to reduce energy loss by using this system, thus making it more resilient to weather and terrorist attacks. In terms of the ‘Zombie Apocalypse’ rating, it’s definitely an improvement for the future.

By purchasing it from your neighbor, you’re establishing a need system whilst also being able to supply them to fulfill that need. Psychologically, it has to make an impact on the community spirit, and certainly will boost the moral.

It is a game changer. Utility companies, beware indeed.
