The total energy requirement of the system (total load) i.e Total connected the load to the PV panel system = No. of units × rating of equipment = 2 × 18 + 2 × 60 = 156 watts
The power used at the end-use is less (due to lower combined efficiency of the system
= Actual power output of a panel × combined efficiency
= 30 × 0.81 = 24.3 watts (VA)
= 24.3 watts
The energy produced by one 40 Wp panel in a day
= Actual power output × 8 hours/day (peak equivalent)
= 24.3 × 8 = 194.4 watts-hour
The number of solar panels required to satisfy the given estimated daily load :
= (Total watt-hour rating (daily load)/(Daily energy produced by a panel)
=936/194.4 = 4.81 = 5 (round figure)
(a) Cost of arrays = No. of PV modules × Cost/Module
= 5 × 8000 (for a 40 Wp panel @ Rs.200/Wp) = Rs.40000
(b) Cost of batteries = No. of Batteries × Cost/Module
=1 × 7500= Rs.700
(c) Cost of Inverter = No. of inverters × Cost/Inverter = 1 × 5000
= 1 × 5000 = Rs.5000
Total cost of system = A + B + C = 40000 + 7500 + 5000 = Rs.52500
[Additional cost of wiring may be taken as 5% of total system cost]
Biogas system design for cooking for a family of six members is considered here. The system design includes the estimation of total gas required, amount of feedstock (or dung), required and the number of animals required to have feedstock of a given amount.
About 350-450 litres of biogas required per day per person for cooking (in engine about 450 liters/hp/hour of biogas is required)
Average production of dung per animal per day:
Cow– 10 kg/day
Bullock – 14 kg/day
Buffalo – 15 kg/day
Other biomass night soil, sugar cane bagasse, maize straw, etc. can also be used)
1000 litres of gas is equivalent to 1 m3 of gas.
Average gas production from dung is about 40 litres/kg of fresh dung.
Retention period of dung slurry in digester is 50 days.
AMOUNT OF GAS REQUIRED PER DAY
I. Number of family members =6 (adult). Considering 400 litre/day/person for cooking, total gas required = 6 × 400 = 2400 litres/day or about 2.4 m3 gas/day.
II. Number of animals required to fulfil daily gas requirement = Amount of gas produced from a kg of fresh dung = 40 litre/kg.
III. Total amount of dung required = Total gas required/Gas per kg of dung
= 2400/40 = 60 kg.
IV. Thus, in order to have 60 kg of dung no. of cows required = in order to have 60 kg of dung no. of cows required = 60/10 = 6 cows.
In order to make slurry, water should be added to equal amount of dung.
Total mass of slurry – Dung+ Water = 60+60 = 120 kg.
Volume of slurry per day (specific gravity of slurry is about 1090 kg/m3)
= Total mass of slurry/Specific gravity
= 120/1090 = 0.11 m3
Retention period of slurry = 50 days. Total volume of the digester = per day volume of slurry × retention period = 0.11 × 50 = 5.5 m3 ~ 6 m3.
Dimensions of the digester : Depth to diameter ratio should be between 1 and 1.3
Gas holder tank dimension : The volume of the gas holder tank should be about 60% of the per day gas volume.
