The ISA aims to bring countries together to provide a collective response to the main common obstacles to the massive use of solar energy in terms of technology, finances and capacity. The area of The Earth between the Tropic of Cancer and the Tropic of Capricorn is called the tropical (bright) zone. This is the part of the world where the sun can appear directly above them, and this more direct exposure means that the actual effect of the sun here is greater; Everywhere north or south of this area, sunlight always reaches the earth`s surface at an angle and is therefore less intense.  The sunniest countries in the world are located on the African continent, from Somalia in the Horn of Africa, east to Niger, west and north to Egypt.  The framework was first released in 2016 to support countries. It focuses on global relevance and local benefits for all countries through cooperation, with the ISA`s key interventions focusing on preparedness and empowerment activities, risk mitigation and innovative financing instruments to facilitate the promotion and deployment of solar technologies in target markets. After receiving the required ratifications/approvals/acceptances of the required number of ISA member countries under the Framework Agreement, the amendment went into effect on January 8, 2021, the State Department (MEA) said in a statement. The United States is the 101st country to sign the ISA Framework Agreement to catalyze the global energy transition through a solar-powered approach, according to the statement. At the signing of the framework agreement, Kerry said in the statement: “It has taken a long time and we are delighted to join the International Solar Alliance, where Prime Minister Narendra Modi has taken the lead.
We have worked out the details and it is a process in which we will be happy to participate. As on January 15 of this year, 89 countries signed the ISA Framework Agreement and of these, 72 have deposited their instruments of ratification, he said. The entry into force of the amendment to the ISA framework agreement will allow all UN member states to join the group, including those outside the tropics, he said. The objective of the ISA is to mobilize member countries, gather commitments from international organizations and mobilize the private sector, support rural and decentralized applications, access to affordable finance, solar mini-grids on islands and villages, rooftop installations and solar electric mobility technologies. The initiative was launched by Prime Minister Narendra Modi at the India-Africa Summit and a meeting of member countries ahead of the 2015 United Nations Climate Change Conference in Paris in November 2015.   The International Solar Alliance Framework Agreement was opened for signature in Marrakech, Morocco, in November 2016 and 200 countries have acceded to it. He added that this will be an important contribution to the faster deployment of solar energy worldwide and especially important for developing countries. India, with the support of France, invited nations to facilitate infrastructure for the implementation of solar projects. The alliance has committed to investing a trillion dollars and is committed to making the cost of solar energy more affordable for remote and inaccessible communities.
The alliance will help India achieve its goal of generating 100 GW of solar power and 175 GW of renewable energy by 2022. Countries support each other in research and development, as well as in other high-level activities.  It is also seen by developing countries as an alliance to form a united front and conduct research and development activities for the production of solar installations in developing countries.  For India, the possible additional benefits of the Alliance could include strengthening relations with major African countries and increasing goodwill for India among them.   The following countries are the potential members of this alliance that have signed the framework. Countries marked with a plus have also ratified the framework.  Afghanistan, Bahrain, Belarus, Belgium, Belize, Bhutan, Botswana, Brunei Darussalam, Bulgaria, Cameroon, Congo, Denmark, El Salvador, Grenada, Guatemala, Haiti, Ireland, Jamaica, Liberia, Luxembourg, Maldives, Myanmar, Oman, Paraguay, Philippines, Romania, Saint Lucia, Saint Vincent and the Grenadines, Samoa, Thailand and Trinidad and Tobago are the last members of this alliance. The Alliance is a treaty-based intergovernmental organization.  The International Solar Alliance Framework Agreement was opened for signature in November 2016 in Marrakech, Morocco, on the margins of the Marrakesh Climate Change Conference (the twenty-second session of the Conference of the Parties or COP 22). The first day (15.
Sixteen countries have signed the agreement: India, Brazil, the Democratic Republic of Congo, the Dominican Republic, the Republic of Guinea, Mali; Nauru; Niger; Tanzania; Tuvalu; Cambodia; Ethiopia; Burkina Faso; Bangladesh and Madagascar.  Guinea-Bissau, Fiji and France also signed the agreement on 17 November.  On November 6, 2017, Indian Foreign Minister Sushma Swaraj met with Guinean Foreign Minister Mamady Touré. During this meeting, Mamady Touré presented Guinea`s certificate of membership in the International Solar Alliance (ISA) initiated by India. Vanuatu and Liberia have also signed the agreement.  To date, 74 countries have signed the ISA Framework Agreement and 52 countries have ratified it. With ratifications from 15 countries, the ISA becomes a treaty-based international intergovernmental organization and is legally recognized as fully operational by the United Nations. Subsequently, 107 other countries joined the agreement, including all major countries located between the tropics of Cancer and Capricorn, including Mexico, Peru, Chile, Paraguay, Brazil, India, Argentina, Australia, New Zealand and China. On November 30, 2015, a conclave for the sun group InSPA (International Agency for Solar Policy & Application) began.  In line with Prime Minister Narendra Modi`s vision to universalize membership in the International Solar Alliance beyond the tropics, the first ISA General Assembly adopted on 3 October 2018 the amendment to its framework agreement to extend the scope of membership to all UN member states. Previously, MEMBERSHIP in the ISA was limited to 121 countries that were partially or entirely in the tropics. This has not allowed major solar energy economies like Germany to join the alliance, which is increasingly seen as a foreign policy tool.
