There are many reasons to purchase a battery system for the home or business, starting with natural disasters, but a battery system, tied into a solar system, will maximize self-consumption of solar power, reduce grid costs, increase the resiliency of electricity, and take a home or business completely off grid with minimal fossil fuels.
Currently, wind generation sites are the cheapest version to build in the United States. Solar tends to be significantly more expensive to develop and construct. Creating one site for both forms is much more affordable, yet offers all the advantages covered above.
The need for renewable energy is high, but governments need to commit to salvation of the future. Short-term goals shouldn't come at the cost of our future.
ARNOLD GUNDERSEN for Bulletin of the Atomic Scientists: My own experience near solar arrays in Fukushima Prefecture indicates that the problems of building and maintaining solar installations in a contaminated nuclear wasteland are over-simplified, and worse, totally ignored. One of the greatest burdens of maintaining operating atomic reactors is the cost of working in a Radiologically Controlled Area. (The Lawrence Berkeley National Laboratory defines a Radiologically Controlled Area as: “Any area to which access is managed to protect individuals from exposure to radiation or radioactive materials. Individuals who enter Controlled Areas without entering Radiological Areas are not expected to receive a total effective dose equivalent of more than 0.1 rem (0.001 Sievert) in a year.”) Each nuclear power plant operates with specific instructions and constraints, with Radiation Work Permits tailored for each specific maintenance activity. Because special clothing, special respiratory equipment, and special radiation monitoring equipment are routinely required to perform even minimum maintenance activities inside a nuclear power plant, every activity takes longer, costs more, and requires more people inside each reactor than necessary in any other industrial setting. Consequently, the question becomes: Does building solar panels on land contaminated with nuclear waste resemble work in a normal industrial setting, or is it more similar to work inside a radiologically contaminated atomic reactor—at significantly higher cost?

Energy Returned Over Energy Invested - a concept introduced in a paper by Dr John Morgan, which I found in Principia Scientific under the heading The Catch-22 of Energy Storage.
When customers can make choices in the energy market with their own dollars, the end result is that they are not only more aware of the market, but also able to direct future investment in energy infrastructure.
It's our opinion that neither performance nor profits were really to blame- but the industry itself. They simply shot the messenger.
What scientists, engineers, companies, and nations expanding their power capacities need to focus on, is implementing solutions that keep negative impacts of renewables in check.
Fossil-fuel industries are boom and bust. Renewables don't have to be.
Today, Texas only has 200 MW of solar capacity, less than New Jersey, Massachusetts, and a handful of other states.
Going solar should be a great experience - not a headache, and doing your homework upfront will give you something money can't buy - peace of mind.
Businesses need to invest in back-up renewable power systems to insure that they can continue working during and after a disaster. With such installations, businesses can prevent interruption losses caused by grid failure.
As more species and cultivars are proposed to help meet the substantial renewable energy needs of our nation, more risk assessments will be necessary to identify the truly green renewable alternatives to petroleum-based energy sources.
Amongst the numerous measures the world has taken to wean itself off the fossil fuels, only a few have been successful in making the businesses, homes and vehicles more energy efficient. Various psychological and financial barriers have kept governments and organizations from realizing the actual potential of energy efficiency programs.
Command economies may be terrible at some things but when the rapid marshalling of resources is needed to solve a problem they can be very good at doing whatever it takes.

Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
