Solar Truss Roof Kerala | Solar Panels For Home With Inverter & Battery Malayalam | KSEB Subsidy

[@solarpark626]

ഞാൻ sir ന്റെ video കാണാറുണ്ട്. ഈ video ഇൽ കുറെ mistakes ഉണ്ട് . താഴെ പറയുന്ന കാര്യങ്ങൾ കൂടെ ശ്രദ്ധിച്ചാൽ നന്നായിരിക്കും. സോളാർ Truss ചെയ്യുമ്പോൾ Angle ശ്രദ്ധിക്കേണ്ടതാണ് south facing ഉം 11 മുതൽ 15 degree ക്കിടയിൽ ആയിരിക്കണം. സാധരണ ഓട് ഇടുമ്പോൾ Rafter or കഴുക്കോൽ angle കുറഞ്ഞത് 25 degree engilum ചെയ്യാറുണ്ട് angle കൂടുന്നതനുസരിച്ച് Roof ന് Safety യും ഭംഗിയും ഉണ്ടാകും. ഈ പറഞ്ഞ angle ൽ Truss ചെയ്യുകയാണെങ്കിൽ electricity generation കുറയുന്നതാണ്. angle 15 ന് മുകളിലോട്ട് പോകുംതോറും electricity production നെ ബാധിക്കുന്നു. Truss ചെയ്യുമ്പോൾ angle ശ്രദ്ധിക്കേണ്ടതാണ്. Solar panel south facing ആണ് fix ചെയ്യന്നത് അത് കൊണ്ട് Gable or Hip roof ന്റെ south facing ഇൽ മാത്രമേ പാനൽ വെക്കാൻ പറ്റു .കൂടാതെ panel clean ചെയ്യാൻ പറ്റണം. കൂടാതെ solar plant മൂന്ന് തരത്തിലുണ്ട്. 1. On grid 2. Off grid 3. Hybrid. Micro inverter advantages and dis advantage പിന്നീടൊരികൽ discuss ചെയ്യാം.

I had this idea 5 years ago but didnt know who to approach to get done in my home town Kollam. My idea was based on getting something built like a car bay canopy on my roof which had a gentle curve and looked aesthetic and was willing to spend up to 25 lakhs. 80 metre square is the floor area I had on my terrace so I am guessing 12-15KW installation or 96kwh-120kwh per day of output.

It will be better if method cleaning solar panels and cleaning frequency etc addressed. In most of the cases such panels are fixed on top of the truss roof and approach to such places are very difficult. Most of the suppliers are silent when they canvass such products. I am one of the victims. As per Kerala's weather condition, rainny season is very muvh thete and hence most of the houses are fitted with truss to protect the concrete structure from rain. This warrant one to go for solar panels above already built truss. During summer dust is accumulated and during rainy season fungus like matter is deposited and unless these deposits ard not removed the output willnot be as per the design. These things arr not informed at all in any of such description. Method ov removing such deposits without damaging the panel also importantant. Hope such details also willhe addressed for understanding of public.

Sure .... Please send a WhatsApp message to 9544036600

[@boywithredcam8517]

Why are you not explaining about the angle of panel placement ? Max output for a micro inverter ( enphase ) is 295 vA that means maximum output of a solar panel above 430 Wp is wasted .please add more details including datasheets. Angle of panel placement also affect the production .Roofing with solar panel will compramise with the output power generated ( rules of angle of reflection and refraction have effect)...

[@Sauhardam]

The angle of slope appears to be wrong. Required angle is 10 degree. Here it appears to be about 30. 10% reduction in output should be expected.

[@firoskattilakam4100]

​@@SauhardamEven for bi facial panels angle of installation is very important. It can reduce the efficiency of not proper. Mechanical engineers may not understand the technical details.

Any tips to determine solar KW requirement for a under-construction home.? We don't have electricity bill yet to calculate the requirement, but assuming there will be 4 ACs, Refrigerator, Oven, and enough lighting and fans, could you suggest an appropriate KW we will need?

[@Sauhardam]

These gadgets are certainly not going to run on a conventional grid tie system unless you invest on a microgrid. With all the gadgets you mentioned, consumption may be 50 units per day, 1500 kWh consumption and a monthly bill of 15000/-. A 10 kw , grid tie system can save you 10k . So you need to invest on a 15kw system. Approx cost 6-8 lakh rupees. Your house, connected load should be 15kw to get approval for a 15 kw rooftop system. These are only rough calculations. If you consume only 30 units per day, a 19KW system is good enough. Go in for bigger companies. I am using a 10 KW grid tie system, one kw off grid system with 10KWH battery back up and 3.5 kw inverter. The system also has a 1.5 kw wind turbine. Good luck!

[@Sauhardam]

For 30kw consumption, use a 10 kw grid tie system!

[@nomad4273]

@@Sauhardam thank you for a detailed explanation. Not sure we would be using 50units or even 30 units for that matter though. Our current (rented) home also has most of these gadgets but I guess the daily use is 20. Will have to see.

[@sajytvm4367]

The kind of gadgets listed in the question by Abhijith, should have a yearly average consumption of about 40 unit per day in a place like Tvm/Ekm. The 20 units theory is unbelievable - it may be a winter month bill or in Idukki district. You have to consider yearly average. It is recommended to have (40+10)/4 = 12KW 3 ph system (10 units is for future gadgets in Kitchen, like electric pressure cooker, deep fryer, Air fryer, dishwasher, microwave oven, ceramic cooker, Multi cooker etc. etc. of a modern family)

ഒരു കാര്യം അറിയാൻ ആഗ്രഹം ഉണ്ട്. വീടുകളിൽ low power systems വയ്ക്കുകയാണ് നല്ലത്! ഇപ്പോൾ BLDC fans 12/24 വൊൾറ്റിൽ പ്രവർത്തിപ്പിക്കാം. അതു പോലെ വീട്ടിലെ ലൈറ്റുകൾ 12-24 വൊൾറ്റിൽ പ്രവർത്തിക്കുന്ന LED system ആക്കാൻ കഴിയുമോ? ഇവ, DC മാത്രം ഉപയോഗിച്ച് പ്രവർത്തിപ്പിക്കാൻ കഴിയുമല്ലോ. ഇൻവേർട്ടർ ഉപയോഗിക്കുന്നത് high voltage,high current loads മാത്രമാക്കാൻ കഴിയും!
