Outdoor Installation We did this installation yesterday, the client already has a Back up system and wanted to upgrade to Hybrid. Secondly he wanted the system to stay outside the house, so we built an outside rack and mounted it outside.

Charpell: Outside the house? does that mean inverter will constantly be on standby or is it remote-controlled. |
Re: . by Charpell(m): 6:12am On Jun 16, 2016 |
baaliyah:The Inverter has been upgraded to a Hybrid system, there sun is sufficient to keep it on for 24 hours. To see the difference between Back-up, Stand alone and Hybrid System, follow this thread https://www.nairaland.com/3141574/building-house-want-incorporate-solar |
Re: . by MrSim(m): 1:57am On Jun 19, 2016 |
Hello. I use a 1000 Watt inverter, powered by two(2) of 200AH deep cycle batteries. From time to time, the city power goes off, AC Output indicator meter deflects to 0, from 2 to 5 seconds, even without electric power interruption. When on bye pass (i.e inverter off mode), it cuts power supply to my electronics. The cutting off of supply to my equipment can be avoided by turning on the inverter. What is the cause of that (City power going off and on without interruption of main electric supply)? Prompt response anticipated please. Thank you. |

Charpell:hi I need a solar system to power a 1.5hp pumping machine, how much will it cost? Do I need batteries and inverter? since I will only run the pump once a day for about 3hrs in daylight. |
Re: . by Charpell(m): 6:19pm On Jun 21, 2016 |
grafikii: Yes you will need inverter and battery |

Just seeing this. Please can you give me a quote for a 3.5kva inverter inclusive of batteries and solar panels to charge it? Will a 3.5 kva carry a refrigerator and or a freezer?. Also I have 1.5kva Luminous inverter with 2 12V, 200ah , what solar panel will charge the batteries and the cost. Awaits your response. |
Re: . by hathway: 3:50am On Jul 18, 2016 |
iamsuskay:i think best configuration for 8 hours back up time of your house power is 8 pieces mono solar panel, one 60A 24V MPPT, 4 pieces 200ah solar batteries, one 3.5kva solar inverter. Also you can use 1.5 solar inverter, but it will need 3 pieces 30A PWM controllers and more cables to connect, it will cost you more money. so use 3.5kva is the best, also in this system you can use more electric appliance , except air conditioners. |

Here is a side note to all of you who would like to power a freezer and a fridge as well. There is an additional way to store energy: instead of storing electricity into chemical compound in a battery, use thermal energy as well, because it is more efficient and cheaper. Put one or several plastic bottles with salt water into the freezer. But leave some air, so the water has room to expand. When you have light (and solar during the day), run the freezer. The frozen ice will "save" the energy and absorb the "heat" from the frozen food. Or you can take the bottles into your fridge. The amount of salt needs to be calculated properly in order to lower the freezing point under 0° C. (Just for your general understanding: In Northern Europe, where you have ice and snow in winter, people use a mix of salt and sand to throw onto the streets. The salt lowers the freezing point, so the ice melts. But this only works for certain temperatures. If it's colder than, let's say, -10°C, then salt won't help.) 1 Like |

Solar energy: Do you live in the south or north? You need to consider your location as well. Here is the insolation for Lagos on a monthly basis. Total global insolation means the total energy of the sun that shines on a surface of one square meter (1x1m) during a year. The metric is 'kilo (=thousand) Watts Hour per square meter and per year'. This translates to a specific solar energy production per year. Specific to a given location, e.g. Lagos (= latitude & temperature). The metric is: x kWh/kWp per year. This metric tells you how much solar energy you will get on a 1000 Watts(peak) solar installation on the roof. This is used to compare the quality and efficiency of each solar installation at a give location and to compare the insolation between different locations. This takes into consideration: a) type of solar cells (mono- or polycristalline) b) type of installation (rooftop, ground, partially shaded) c) tilt/inclination of the solar modules or if it is on a single-axis/dual-axis tracker. kWp = kilo Watt(peak) = at peak power; The value Wp or Watt(peak) is found on the name/type plate on the back of the module. This value is measured under laboratory conditions with a flasher (1000 Watts/m2, 25°C, ambient air pressure) . Since the solar cells are semiconductors, solar cells are less efficient when they get hot. With every degree above 25°C the solar module gets less efficient. It is called Power Temperature Coefficient in % per Kelvin, e.g. -0,30 % per Kelvin.

So, a solar system consisting of four modules with 250 Watts(peak) each is 1 kWp. Total solar energy production = Size of solar system in [kWp] * Specific energy production at the given location in [kWh/kWp*a] 1 kWp * 1.648 kWh/m2*a (Lagos) = 1.648 kWh total solar energy production per year (-> on the roof!) Daily energy production on average = 1.648 kWh/a / 365 days = 4,5 kWh or 4.500 Watts Hour per day (-> on the roof) Due to energy losses of solar charger and inverters the efficiency of direct usage (not stored) is approx. 80%. 4.500 Watts Hour * 80% = 3.600 Watts Hour. If you store the energy into batteries there are losses while charging and discharging, you can feel the heat of the batteries. Batteries in good conditions have a 90% efficiency. (4-5% for charging and 4-5% for discharging). Let's say 1/3 is used directly = 1.200 Watts Hour during the day and 2/3 is stored 2.400 Wh * 90% = 2.160 Watts Hour. Total energy available = 3.360 Watts Hour (24h day with storage) Of course, there are rainy/cloudy days.
