PHOTOVOLTAICS ALLOWS YOU TO HAVE YOUR OWN POWER PLANT


Even today everyone can make his own power from PV modules and supply it to the power grid. 



ENERGY PRODUCTION

Energy production in PV systems is connected to irradiance in specific month. In Photovoltaics air temperature is not as important aspect as in solar collectors. In PV situation is even flipped over - cooler module produces more energy than warmed up module under the same light condition. Due to that PV systems can produce power even during winter. 



Hybrid PV systems - method of saving energy.


One of methods of saving energy, needed for running electric systems in home is hybrid photovoltaic system. PV power plant is important element of grid energy saving, as example in industrial environments, shopping centers, office buildings or schools energy generation reduces long term costs of exploatation. This is main reason for building PV power plant. 

Energy generated by PV power plant via the inverter, is transferred to electric utilities to satisfy current needs. Depending on number of online energy consuming methods, energy may be used from power accumulators used primarily for water heating in boilers. If overproduction is not used power is sold to external grid energy distribution grid, or inverter will lock the power plant. This case is most common around the noon during sunny days, when most power is generated, and home appliances are not used, as majority of us are at that time in work. This is reason why very valuable addon to PV power plant is accumulation system consisting of accumulators and power distributors. This kind of PV system, one connected to grid and with accumulators we call 'hybridd system'. Primary role of this system is major reduction in quantity of energy taken from external grid. 

Energy storage system can save energy for future use, as example after dusk or during production flucutation during the day. Such system can maintain household operation, even if external grid turns offline. In the event of power outage inverter will simulate grid's frequeency. Power plant will work despite issues in grid, and will supply power to the building. 

The downside of power storage system is their higher cost, depending primarily on size of batteries; such cost leads to increased time of investment return in power plant designed in this manner.ni. 




Investment return is faster the higher the energy cost from the power distribution grid. 

Other possibilities in order to reduce energy usage, as example in household, can be done via more power efficient appliances, e.g. energy saving light bulbs, LED lightning, appliances of energy class A+++, A++, A+. Modern appliances have delayed startup, we should use it when we're in work, and power production is highest during the sunny day. 

On information table of every appliance you can see it's annual energy usage in kWh. If you have appliances without such information notes, you can check it's use by connected between power outlet and appliance energy measure system. Such energy counter will show used energy by the device, and it's total use in Wh. Counter with specific precision will check the device, even with very low energy use. Most appliances are used during the day just for some time, thus you can calculate how much energy you need to run necessary devices, and tell us how much energy you'd need stored. This way you can calculate size of energy storage system and size of PV power plant. Other issue is available space on the roof of building or close to that building. 

On the market you can find devices working on low voltage - 12v, 24v, which can use energy from batteries directly, without use of inverter that uses miniscule amounts of energy to work, which will reduce used power slightly. However variety of modules working on such voltage is smaller than one of devices working on 230V. Well designed hybrid photovoltaic system can provide good supply of power, thus provide you with desired energy saving.



PHOTOVOLTAICS SYSTEMS FOR BUSINESS

 



Photovoltaics is a business that is already profitable. Thanks to visible cost reduction of all elements of PV installations, investors can put their money into this technology, expecting reasonable returns. 

Two primary uses of PV power plants for own use, consumed on the spot, not directed towards sale for power distribution company, and building industrial power plants with high power, which with correct founding can be profitable business by themselves. 



Mounting system 

Free standing mounting system is one support system dug into the ground, dedicated to polycrystalline and monocrystalline PV moules' installation. Construction is mounted on single support pushed with tool into the ground. Depth of support is set depending on environmental conditions. It's normally between 1.2 to 1.6m deep. 

Aforementioned structure is very stable and easy to build. Additionally it can be mounted on almost any ground, and terrain shape is rarely an issue. Elements are made from high grade hot-dip galvanized steel Z-600, which provides it with stable anticorrosion layer and long term functionality. 

Such system was used, among other cases, in building of one of biggest European Photovoltaic farms - in Bautzen. 



Product and Service

Industrial free standing power plants are independent investments, created to produce energy, intended to be sold to the distribution grid. In these power plants full product includes entirety of elements of installations from fences, ground preparation, support system installation, PV modules installation, inverter installation, cable installation, grid connections to actual connection to grid, safety systems, effieincy monitoring and visual monitoring. 

Photovoltaic power plant consist of full analysis of building, both when it comes to roof, it's shaing areas, building's power use, but also - checking any energy installation or connections to the grid. Installation includes mounting system, holing PV modules in place connected either to walls oor roofs. It also includes mounting of modules, inverters, cables and efficiency monitoring. 

Other elements are dependent on individual investor choices. 

All installations are periodically checked, and standard reaction time should not take longer than 48h. We have group of experienced electricians and technicians, who can swiftly fix rarely occuring problems. Most of devices we use in our installations have 5 years warranty, with PV modules having them longer. Some have even 25 years producers warranty.

How Companies are Losing Billions (yes, Billions) by Not Going Solar
With U.S. commercial electricity prices at their highest point in nearly a decade, many businesses are looking to solar to meaningfully increase their bottom line and drive incremental enterprise value.
The value that solar can create for businesses becomes especially staggering when you look at how many low-margin industries have energy costs as a meaningful percentage of overall revenue, and therefore how small changes in energy costs can greatly improve company profitability.
For sectors from agriculture to mining to waste management, a 30% reduction in overall energy bills can improve net margin — and therefore enterprise value — by over 45%. Even industries with a more modest energy bill, like real estate development, retail, and food and grocery, can still achieve double digit increases in profitability.
In the 18 industries below, these savings equate to over $25B in Net Income and $770B in Market Cap. That’s a lot of money to leave on the table.

Said another way…

Among the many ways to cut energy consumption, solar is a top choice for three reasons
1. Innovative financing
Power Purchase Agreements (PPAs) have revolutionized solar financing by allowing businesses to lock in (nearly) risk-free savings for $0 down. The concept is simple: a third party pays for the installation of solar on a business’ roof, charges the business nothing up-front, but locks the business into a long-term (usually 20 year) contract to buy the energy produced from the solar installation at a predetermined rate (the PPA rate) with a fixed escalator (usually around 1–2% per year).
Since the PPA rate is lower than the retail price of electricity, and the system is owned and maintained by the third party, businesses have limited risk from entering into this type of agreement. In addition to PPAs, there are solar leases, traditional loans, and even Property Assessed Clean Energy (PACE)loans that are repaid through property taxes.
The shift towards Third Party Owned (TPO) systems like PPAs, where the business who has solar on their roof does not actually own the system, has been dramatic. This trend is encapsulated well by the New Jersey Clean Energy Program interconnect data, which shows the share of installed solar capacity from TPO systems spike from 12% to 73% in just one year.

2. Tangible, predictable savings
In any capital investment, having a clearly traceable and highly predictable ROI is critical for financiers (who must backstop the asset) and system owners (who want to ensure that their investment pencils out).
Solar energy system output is easily measured with an energy meter, which makes its impact straightforward to quantify. When it comes to prediction, there is a wealth of historical climate data available from organizations likeASHRAE, along with solar energy system design and performance tools likePV SystFolsom Labs, and now Google’s Project Sunroof, to provide high accuracy estimates of future energy savings.
3. Minimal disruption to the core business
Solar does not require a behavioral change on the part of employees or customers, or an aesthetic change to the inside of the building, in order to accrue savings. By allowing companies to run their business as usual, they can take advantage of the benefits of solar without bearing the costs of productivity disruptions.
These favorable dynamics have precipitated a steep growth curve in the U.S. commercial solar market, with installations growing nearly four-fold from 2010 to 2015 according to I.H.S. Solar

What’s the catch?
While these high-level facts make commercial solar an attractive investment, there are important risks that must be mitigated in order to ensure that commercial solar systems are performing optimally.
