Major photovoltaic (PV) inverter manufacturer Sungrow Power Supply Co has said the largest floating PV power plant with a capacity of 40MW had been grid connected on former flooded coal mining region in Huainan, south Anhui province, China.
Floating solar power plants are becoming increasingly popular across the globe due to their ability to reduce water evaporation in many applications, while the cooler ambient air, due to the water location, notably in hot and humid environments, limits the solar panel’s exposure to the ‘temperature coefficient’ that results in performance degradation as ambient temperatures increase.
Sungrow said that its central inverter SG2500-MV central inverter was deployed at the floating plant that featured the integration of the inverter, the transformer and the switchgear, as a turnkey station. In addition, the combiner box SunBox PVS-8M/16M-W supplied by Sungrow was customized for floating power plants applications, enabling it to work in a stable condition in such and environment with high levels of humidity and salt spray.
The floating plant is located on flooded land with the depth of water ranging from 4 to 10 meters, according to the company.
A 20MW floating system in the same region had been the largest operating since early 2016.
Tesla began taking orders for its solar roof tile products as of Wednesday.
CEO Elon Musk revealed on Twitter, that the company would begin taking orders for any territory.
In response to a number of questions, he confirmed that UK “delivery and installation” would begin next year. US deliveries will start before the end of 2017.
The initial orders will be for the black smooth and textured tiles with the Tuscan and French slate models following six months after.
According Tesla’s most recent quarterly results, manufacturing of the tiles will begin in Q2 2017.
“We plan to start pilot manufacturing Solar Roof tiles in the second quarter of 2017 at our Fremont Factory. Shortly thereafter, production will transition to Gigafactory 2 in Buffalo, New York. Our partner, Panasoni c, will provide capital and operational support to manufacture PV cells, thus enabling high volume integrated tile and PV cell production at a single facility,” the company said.
The tiles were first revealed in October 2016.
These tips stem from many years of experience working with multiple industries and companies. I have seen both ends of the spectrum when it comes to written agreements. I won’t represent a company that is poorly represented on paper. I wouldn’t feel right offering a product or service to someone that I am not passionate about myslef. I am a huge advocate of clarity and transparency. I wouldn’t expect a customer to sign anything I wouldn't myslef.
1. Roof, Home and System Warranty
Your property is an asset. You want to protect it the same as any other asset that you have. The best way to protect that is by warranties and guarantees offered by the company. If they want to put equipment on your roof or anywhere else on your property, you need some guarantees that protect you.
First, is your roof. Solar panels require mounts which means holes will be drilled into your roof. You need to make sure that the solar company or construction company installing the panels gives you at least a 5 year roof warranty. That will provide ample time to ensure their installation has not caused any issues.
Second, is the system warranty. Most manufactures will give you a 25 year manufacture warranty. Some inverter companies will also give you a 10 year warranty. Make sure you are getting both a company warranty and a manufacturer warranty.
2. Production vs Consumption
It is very importnt to look at how much electricty you are currently using on an annual basis. This is the foundation of calculating that you are getting the appropriate amount of electricity from your solar installation. Take into consideration any future home improvements like roofing, windows, HVAC, or additions to your usage like electric vehicles, pool, spa, etc. All of these factors affect what your electric needs will be in the future. This must be assessed and factored in to the size of your solar array in order to ensure your needs will be met both short and long term.
3. Moving Options
What happens if you move? That is an important question for any property owner. This should be outlined as a simple process. You should be able to easily transfer your solar to the next home owner. That’s the most popular option. There are usually other options like the new owners buying the system outright if not already paid for. Some companies will let you take the system with you, however that is typically not in your best interest. If you paid cash for the system, studies show that, on average, you should get 90% or more of your investment back. Unlike kitchen remodels, for example, you only get roughly 60% of your investment back. That is huge!
4. Understanding Your Project Details
Make sure you know what you are buying. That means all of the above as well as knowing the type and quantity of equipment your are getting, as well as how much the system will be producing. If you know that you use 12,000 kWh a year and are being sold a system that will only produce 9,000 kWh, that will not cover your need and will still leave you owing money to the power company. If they tell you that you won’t have a utility bill, kick them out. You will owe the utility company for that 3,000 kWh. Make sure the numbers add up. Make sure you’re getting the most value. Also, is it a purchase, lease, or PPA? Each program has it's own pros and cons. So make sure you know what you’re paying for and how.
5. If it’s not on paper, it’s not part of the deal
If the consultant says one thing but can’t prove it in the contract, don’t sign it. Verbal agreements don’t hold up. If they tell you all about their warranties and guarantees but can’t show you where it is in the paperwork, don’t sign it.
My main goal here is to prevent you from doing business that will not serve your priorities and bring you the most long term benefit. Only commit to an agreement that provides for all of your energy conservation wants and needs at a fair price.
