In 2021, the Securities and Exchange Commission (SEC) has provided information on
cryptocurrencies, with up to 1.165 million new account openings, whereby the value of cryptocurrency
trading in Thailand is 44 million baht and 632 million baht, in 2020 and 2021, respectively. Cryptocurrencies

play a role in society and the economy. Verification of transactions on blockchain for cryptocurrency rewards
has become a new business for Thai investors, in which obtaining of such rewards has electricity costs
charged by the State, which is an important variable to the return on investment, which also comes at the

cost of environmental resources that leads to “Global Warming”.
The study of the use of solar cells to verify transactions of cryptocurrencies on a blockchain system
located in a residential building of Thailand is an analysis of the properties and amount of electricity from
solar cells, which is sufficiently used to verify transactions on the cryptocurrency blockchain. The analysis

and relevant calculation are referred to the electricity generation from solar energy handbook of the
Department of Alternative Energy Development and Efficiency. This research will lead to the determination
of the most suitable off-grid solar cell configurations to verify cryptocurrency transaction on blockchain with

the use of GPU. This results in electricity cost savings of 24.17 baht per day or 8,822.05 baht per year, where
payback period for the solar cell is approximately 5.1 years . Considering the cost of electricity and returns
to outcomes of this will provide options for energy savings from the use of renewable energy for those who
are interested in investing in blockchain transaction verification in residential buildings located in Thailand.
