When Should Not Buy Solar PV Systems?
If your building/house is heavily shaded. As the shadow will dramatically reduce the solar system generated output electricity. In your vision you have to take care and consider about the impact of the current shadow and the anticipated shadow comes from trees grow or known renovations and extensions in surrounding buildings, that what we called shadow analysis study. It is an important study assisting us deciding whether the solar system will be a good beneficial investment project that worth to proceed or not. One more thing to note, is that in case of locations subjected to such shadow, its recommended to use micro solar inverter, so you can distribute your solar panels freely and avoid areas with heavy shadow.
Solar photovoltaic System Application in Our Daily Life
One of substantial financial saving we can get from solar photovoltaic system is to make what we called "load shift". It means to shift electrical power usage from night times to daylight times in where the sun is shining and the solar system generates such free electricity. We strongly recommend to run your high power equipment in day light time, like dish washer, clothes washer, pool pump, dryers, water heater, electric heater, electric cars, etc. By this way you can make big financial saving and avoid paying high electricity bill to the electric utility. Also, it is worth to pay your attention to using timer to achieve smoothly operation of such equipment to daylight hours, it will be very helpful way to avoid the forgetting.
Best Solar Battery for Solar PV System
There are two main types of solar batteries in the market; Lead acid and lithium. Although adding such batteries to the solar system will add extra significant expenses on solar system price, but it has much benefits; It will reduce our electricity bill, and we will be independent of the grid keeping our equipment work in case of grid interruption, and this is critical high value benefit in places/areas prone to grid blackout or even has no connectivity with the grid, and specially for some kinds of sensitive equipment like fridges, freezers, and medical equipment.
How to Increase the Financial Return of your Solar PV System?
The solar photovoltaic system power generation in sunny day is approx. 4-5 times the cloudy day, so we need to delay operating our big power capacity appliances, like dryer, washing machine, and dish washer in cloudy day to the next sunny day. In general, when solar generation is low then do Not run all your appliances at the same time, and delay those which can be delayed without harming your lifestyle to the next sunny day, in order to avoid purchasing electricity from your local grid and pay more for your electricity bill. So, please do your jobs in sequence rather than doing them simultaneously. Also, for your Air conditioner, you can pre-heat or pre-cool your home at daylight time, so stored heat or cool on your home wall will provide a comfortable whether in the evening. This way can save you much money compared to the Air conditioner regular operating time from 5pm To 9pm when usually the household returned back to home.
3 Factors Affect Solar Photovoltaic System
One of the most external factors affecting solar photovoltaic performance rather than the 3 factors aforementioned, is how much solar irradiation exists in that country/location. There will be many calculators available on internet free of charge that provide us with accurate sun irradiation data for each place in the world. This calculator estimates the output power from the solar photovoltaic system based on optimal criteria, means best orientation, best pitch angel, no shadow, and standard good quality solar panels.

Calculate Payback Period of Your Solar System
Payback period refers to: In how many years our solar system will return back its fixed and running costs we should pay for. Basically, before proceeding in purchasing/installing any kind of solar system and due to their high initial costs, we need to make economical feasibility study to know how to calculate the payback period and whether this solar system will be profitable project or not.
How to Save Money with Solar System?
The electricity consumption in homes differs based on home size, number of resides, home wall insulation, heating/cooling system presence/ capacities, number/ type of electrical appliances, and of course the life style. So, large homes with pools, and air conditioning units will exhibit high consumption with high electricity bill more than small homes, and always the home owners are looking forward to reduce the consumption/bills which is critical in large homes. In fact, there will be 2 main opportunities to reduce electricity consumptions and save your money.
Buy Best Solar Inverter for Photovoltaic System
When sizing the solar photovoltaic system, we should mind some logic important factors that have substantial effects on solar system itself and our electrical appliances/equipment: 1. If we don’t use the electricity generated from the solar photovoltaic system during the daylight hours instantaneously, it will be exported back to the power grid if we have grid tie solar photovoltaic system type.
Solar Inverters: Advantages and Disadvantages
Solar inverter is an important electronic device which converts dc electricity generated from solar panels photovoltaic system or dc batteries system to ac electricity that can be used to operate our household appliances, commercial/ industrial buildings...etc. The solar inverter mainly consists of step-up transformer, voltage regulator, mosfet driver and some other small electronics components.
Solar Photovoltaic vs Solar Hot Water
Solar photovoltaic system converts sun lights to electricity, but solar hot water system and also called solar thermal system converts direct heat gained from the sun to hot water. So, they are 2 different amazing technologies to make use of the unlimited sun energy. In solar photovoltaic system, when the sun lights hit the solar panels surface, an electric direct current is generated and flow over the electrical wires/cables, then it is going to an Inverter which does convert this DC Voltage To AC voltage which is usable for all of our electrical appliances/equipment. So, it’s not complicated system, its simple and profitable project on all scales.
How to Choose the Best Solar System Components Brand?
In the market you will find many numbers of companies that provide solar components, and for each solar professional, you can take advice from, his certain recommended products, and each solar professional will provide very convincing reasons standing behind his choice. So which opinion you can trust, and which product is really the best?
How to Calculate Your Solar System Payback Period?
Before implementing any type of solar systems projects, whether it is On Grid or Off Grid solar system, we need to calculate the return on investment of such project, and to be more specific, we need to calculate how much money we will harvest? In other word, how long does it take for the solar system project to pay for itself (payback period)? And what is the extra money we can get after the solar system project returned the expenditures we paid for it.
8 Tips to Select Off Grid Solar Inverter
There are 8 tips to consider when selecting the proper off grid solar inverter, let us see as following. 1. The off grid solar inverter output voltage and frequency. This will base on your load requirements and usually its same as your country standard supply voltage/frequency. 2. Installing off grid solar inverter or hybrid inverter. Most of off grid solar inverters and hybrid solar inverters have AC backup supply connection, so the inverter bypass to use it for feeding your loads in case of sun absence and batteries discharged. Moreover, you can use this AC backup supply to charge the batteries through internal solar inverter batteries charger.
On Grid vs Off Grid - Which is the Better?

Buy Grid Tie Inverter for Your Solar System
Grid tie system is a solar system incorporates solar panels, grid tie solar inverter and other components to convert sun light into usable AC electricity while your house/premises remain hooked up to the electric utility, consequently your house still be fed with electricity even after the sun light disappears at the night (from the electric utility), and at the day time, the solar system will take the responsibility!
Is Solar Micro Inverter Worth buying?
If the solar system is confirmed to be expanded in the future, micro inverters are a good choice. It is easy to continue adding a new unit to the micro inverters. The cost of adding another complete unit to a standard inverter is higher. When the panel faces multiple directions or there is a shading problem, choosing a micro inverter is definitely a value-added product.
How Grid Tie Solar System works?
The more the sun shines, the more DC electricity the solar panels can produce, and the more AC energy we can get. When the AC power is larger than our loads requirements, the excess electricity will send back to the electric power grid allowing other neighbors customers to use this clean solar energy. But if the AC power generated from the solar grid tie system is less than our loads requirements, then our loads will pull extra power required to run properly from the electric power grid. The 2 cases will be done automatically via the brain of the solar system which is the inverter, without any other interventions.
What is the String Solar Inverter?
In string solar inverter, there will be a number of solar panels connected to each other in series, usually a number 6-10 solar panel, and generating what we called string. This string positive and negative terminals “DC” will be connected to the string inverter input side. As the panels will be connected in series, the overall string DC voltage will be high (typically 200-850V) and the circulating current will be low (equal to one solar panel rated current).
3 Different Types Of Solar Inverters
Solar inverter is the brain of the solar system, although its basic role is to convert DC electricity comes from solar panels to usable AC electricity, now it takes the responsibility to monitor and control the whole solar system and provides important technical info required for solar system operation and maintenance crews to fix system errors, in addition to that it takes responsibility to manage batteries system incase of its presence in the solar system.
What is the Solar Central Inverter?
Solar inverter is the heart of the solar plant, it represents the main equipment that converts DC output from solar panels to AC electricity required to run all our appliances/machines/equipment. In addition, it takes the responsibility of monitoring and controlling the PV array system.
