As battery storage solutions advance and become more available, our reliance on fossil fuels will decrease and grid reliability will increase, putting us on the right track to a sustainable future.

Advancing Solar Storage Solutions

Over the course of 2015, the US made leaps and bounds toward establishing solar as its primary source of energy. But one of the major obstacles we face in completely replacing fossil fuels with renewable energy is the storage problem. To run a household, business, or plant solely on solar power, requires continual access to that resource. It is difficult or impossible to get the needed amount of energy at night and on cloudy days using solar panels, which results in intermittent renewable energy resources and reliance on the grid.

Storage batteries, however, can trap the power that the solar cells produce when the supply exceeds demand—for example, in the middle of the day—and then provide that energy when the demand exceeds the supply.

At the moment, storage batteries are expensive, which leads many solar energy users to forget about storage and take advantage of sunlight strictly when it’s available, relying on fossil fuels to get the rest of the job done. In addition to the continued reliance on traditional energy, this poses another problem in certain areas: the growing capacity of solar has created a gap in electricity supply and demand, causing the grid to become unstable during times of the day when solar energy is most accessible.

The solution to this is innovations in storage battery technology, which will spread the excess generation of solar throughout the day rather than lumping it all in the most productive hours. It will smooth out intermittency problems and allow solar energy users to rely less on fossil fuels.

As it stands, the standard lithium-ion battery costs about $1,000 per kilowatt hour, a significant investment for home and business owners already shelling out for necessary solar energy system equipment. But this may not remain a problem forever. In fact, the Energy Department announced in January of 2016 that it will invest $18 million in storage solution development. This will fund six new projects across the US, which will enable storage solutions that are reliable and affordable to consumers.

Right now, one of the most viable battery technologies on the market is a suite of Tesla batteries that Elon Musk says could “fundamentally change the way the world uses energy.” There is a model for residential and business use as well as a model for utility-scale use. SolarCity provides these batteries for 60 percent less than previous storage products, making solar energy storage an increasingly viable solution.

When it comes to the question of whether solar will still be cost effective when the tax benefit reduces at the end of 2016, the answer is a complicated one. It would stand to reason that without the tax benefit, consumers will be less likely to invest in solar energy systems. However, this may force the industry to innovate on a tighter schedule so that consumers can continue to afford solar products.

As battery storage solutions advance and become more available, our reliance on fossil fuels will decrease and grid reliability will increase, putting us on the right track to a sustainable future.

With such a fast pace of growth in the renewable energy sectors, it makes sense that the next step up is to enhance all the storage solutions so we can maximise our gains in these industries. After all, the objective is for the utilities services to produce enough power for all of civilisation which is still growing at such a rapid rate.
We can definitely be looking forward to a more environmentally-friendly future now that battery storage solutions are continuously rising. It is in fact a positive notion for us to take advantage of to further improve this particular industry. We need to act now to tap onto this resource alternative in order to ensure a back-up plan is made available before we run low on fossil fuels.
How interesting that towards the end of the year that this article has come out, Elon Musk introduces his amazing near solar panel roof system. With this, I'm pretty sure we can see the effects of our fight to help save the environment improve a great many fold! Soon we'll be looking forward to other methods of ecological storage space and supporting systems to maximises the benefits from this new technology and things will only continue to improve!

OMG Roofing Products - PowerGrip Universal

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
