Based on external factors, research about internal factors are conducted through individual
questionnaire.
Initial hypothesis of main variables:
1. Participants have large consumption of electricity
2. High income group
3. Large consumption on electricity correlate with attitude
towards expensive
4. Main consumers are those who use large so desire to save
electricity bill.
However, the result
Income*Participation = Irrelevant
Consumption of Electricity*Participation = Irrelevant
Consumption of Electricity*Attitude = Irrelevant
c.f) Respondents with small electricity usage still feel their
electricity bill is expensive

Demographics
• Middle-Old aged • Male • Lower-
Middle class income
Awareness
• Background knowledge of solar
energy
Driven by profit
• Interested in making profits rather
than saving electricity bill.
Profit is deemed as main dependent variable
Attitude towards electricity bill*Compensation = Respondents with small
electricity bill still want to join the business as long as there is profit for them.

Key Variables
Green
Sunlight
Number of users
• The number of people who are using our services and installing the solar
panels in their homes.
Solar panel price
• The price at which solar panels are acquired by our company, either from
the manufacturer or a secondary vendor.
REC weight
• The rate of the Renewable Energy Certificate (REC) that favors energy
produced in environmentally-friendly ways over traditionally produced
energy
Electricity produced
• Amount of electricity generated as a whole by solar panels
SMP Price
• Fixed rate at which electricity is charged by central power company

Past:
There is no need to go back because
the goal of the model is to show
viability of future business.
Future:
The model will look at two cycles of
lease-repayment of solar panels to
customers.
Perception of Problem
Rough Calculation:
Estimated revenue (per customer):
REC sales + Reduction of electric bill (SMP)
3000/month+1800/month
Estimated cost (per customer):
Price of REC + Installation fee + Maintenance
100,000+20,000+2000/month
Estimated period of return: About 4 years

Formulation of Hypothesis on ‘Number of Customers’
1. There is no existing pattern between income level and participation.
2. Those who have prior interest in solar energy (e.g. with knowledge in Tokyo Protocol and solar cells) have
a larger tendency to participate in our Green Energy Grid Project.
3. Those who live in less urbanized areas are more likely to show interest.
4. Those who have vacant space will use more electricity.
5. Those who feel the electricity bill is expensive may have higher electricity usage.
Local Hypothesis
1. There is a positive relationship between number of customers and revenue from REC sales.
2. As the revenue shared to customers goes up, the overall number of customer also goes up.
3. The overall cost of solar panels increase as the number of customers go up, but at a much
slower rate due to economics of scale.
4. As an end goal, the increase in our profit and increase in number of customers will lead to
increased value creation for society, and in addition will lead to positive feedback from
society in general to our business.
5. As total electricity produced by our customers increases, the REC weight will go through a
period of decline and then a period of stabilization.
